VPS 9 (Atlanta) - My Dream VPS!

Presented by @sohamb03 ; Directed by VirMach

Hello everyone!

This is none other than me to present a review on VPS 9 (Atlanta), belonging to the present mega-VPS group of Post4VPS, both in specifications and stock.

THE STORY

I won this VPS on the 7th of September, 2019. I'd casually submitted a VPS request to be honest, I'd never really thought of winning this amazing VPS at the end of the Giveaway. When the Giveaway was on-going, little did I realize that this VPS, which has been an all-time favorite at Post4VPS would be mine. My spirits were really dampened when I came to know that a lot of candidates had applied, and only three of them remaining in stock with about 5 canditates already in the race, I'd assumed I wasn't going to succeed this time.

Destiny was otherwise. On the 6th of September, 2019, @deanhills informed me (oh BTW I has initially applied for the Seattle location) that Seattle was the only location of VirMach VPSes that had a negative VPS review. He suggested that I could choose Atlanta, as Arsal has recently dropped it. I'm glad he made the suggestion that day, and today I take this opportunity to thank him a ton for the suggestion. Arsal is to be thanked too, for dropping this one, to my advantage.

The very next day, came the best news. I did win the VPS and my happiness knew no bounds. Thanks to @Dynamo for organizing this forum, that brought us all together. I must say I've made great friends here, and this VPS - VPS 9, is one which I could've otherwise never afforded myself. This VPS played a great role in improving my skills in the Linux Administration, and it is through this VPS, that I learnt a lot of things.

Agreed that this VPS did cause a lot of trouble during the OVZ to KVM migration, I've very little to complain about as these were very petty problems compared to the great benefit I derive out of this VPS. (FUN FACT: I'd 6 OS re-installations on this VPS, basically I troubled Dean a lot.

)

It's been 9 long months that I've been the holder of this VPS, and its time I justify the VPS and convey my regards and thanks to VirMach, through the medium of this review. Enjoy reading further!

STORAGE BENCHMARK

I've 80 GB of storage on my VPS. In VPS 9, you can choose in multiples of 5, and I didn't need much storage till now, but I'll need more soon with another OS re-installation.

For the boot time: (Actually I've a GUI - XFCE - running on the VPS; not sure why it didn't show up

)

Startup finished in 861ms (kernel) + 2.761s (initrd) + 12.130s (userspace) = 15.753s

Although, the boot time is pretty cool.

USAGE

Here's the most important part - the use case of the VPS lol.

I presently have CyberPanel running on he VPS - and two websites including my speedtest server being powered by the same. Also, I give free web hosting to one of my friend.
I've 6 Discord Bots running on that VPS (3 for me and 3 for yet another friend). All of them are coded in Python, and the server handles the load quite well. Not using much RAM and CPU honestly, except a few occasional spikes.
A GUI - XFCE - is running on the VPS. It's the lightest GUI available (cuz I've previously faced problems with GNOME and MATE).
Development and testing of my scripts.
A private OpenVPN server for myself.
I'd installed Pterodactyl panel initially on the VPS; but on noticing that it consumes a lot of resources and conflicts with other applications on my VPS, I wiped it off.
I always keep aside little resources (which is why the free space) for testing new stuff, panels and beta testing of other applications.

SUMMARY

Let's sum up this review.

1. I'm extremely satisfied with the VPS ... it's perfect for my needs and use-case. I do not regret keeping a considerable space empty cuz they get filled and wiped occasionally.

2. As we all know, VPS 9 doesn't have a control panel, but honestly I never felt the need of having one. Dean and HR have been very active at support and my level of satisfaction knows no bounds.

Again, a huge thanks to VirMach and Post4VPS, for this amazing VPS. Also, thanks for taking time to read this review, dear readers. Although I've tried to keep this review as descriptive as possible, any feedback, suggestions are welcome. I'll try my best to include them as soon as possible.

Regards,

Sayan Bhattacharyya,

Heartiest thanks to Post4VPS and Virmach for my wonderful VPS 9!

Your KVM VPS uses virtio drivers for the disk and those disks in that case all are to be found at /dev/vdX (x = a,b,c...) and the partitions are at /dev/vdXY (y= 1,2,3...).

You have /dev/vda1 which however is just the boot partition. So maybe rather use the LVM root partition to do the tests which is "/dev/mapper/centos-root". Your OS installation uses LVM rather than classic partitions.

@sohamb03

I'm afraid you'll have to repeat all the storage benchmarking section!!

STORAGE BENCHMARK

I've 70GB of storage on my VPS. In VPS 9, you can choose in multiples of 5, and I didn't need much storage till now, but I'll need more soon with another OS re-installation.

Code: (Select All)
Filesystem Size Used Avail Use% Mounted on devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 64M 3.8G 2% /dev/shm tmpfs 3.9G 352M 3.5G 9% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/mapper/centos-root 47G 17G 30G 36% / /dev/loop0 1.5G 9.0M 1.4G 1% /tmp /dev/mapper/centos-home 23G 1.1G 22G 5% /home /dev/vda1 1014M 228M 787M 23% /boot tmpfs 783M 4.0K 783M 1% /run/user/0 tmpfs 783M 0 783M 0% /run/user/5003

For the boot time: (Actually I've a GUI - XFCE - running on the VPS; not sure why it didn't show up )

Code: (Select All)
Startup finished in 861ms (kernel) + 2.761s (initrd) + 12.130s (userspace) = 15.753s

Although, the boot time is pretty cool.

Now for the tests, directly from the Benchmarking Script:

Code: (Select All)
Disk Speed ---------- I/O (1st run) : 799 MB/s I/O (2nd run) : 781 MB/s I/O (3rd run) : 827 MB/s Average I/O : 802.333 MB/s

Which is a remarkable performance!

This is the disk-speed-beta.sh script, not yet merged into the benchmarking script but just a confirmation of the above results plus the cached mode.

Code: (Select All)
Testing hard drive write speed. Pass 1... Pass 2... Pass 3... 693 MB/s Testing hard drive read speed with caching. Pass 1... Pass 2... Pass 3... 2.5 GB/s Testing hard drive read speed without caching. Pass 1... Pass 2... Pass 3... 859 MB/s

(PS: Here I encountered a strange problem. I'm not an expert at all this; since I don't deal with hardware at all. For some reason, my system seems to be missing "/dev/sda" and I've the least idea why, so I performed the upcoming tests on "/dev/loop0". No idea if that makes a difference but nevermind. If I were to make a wild guess, I got CentOS 7 installed from ISO since I needed the default partitions for some purpose ... maybe that's why.)

Why?!.. you may ask!... Simply --and correct me if I'm work-- because you were benchmarking inside the /tmp folder, which is a loop-mounted folder (as /dev/loop0). Thus the rates you got ain't really those of your virtual disk (/dev/vda), but just a loop-mounted folder/device.

Code: (Select All)

Filesystem               Size  Used Avail Use% Mounted on

.....

/dev/mapper/centos-root   47G   17G   30G  36% /

/dev/loop0               1.5G  9.0M  1.4G   1% /tmp

/dev/mapper/centos-home   23G  1.1G   22G   5% /home

/dev/vda1               1014M  228M  787M  23% /boot

....

Those, who did have OVZ editions of VPS-9 will be familiar with the 600/700 MB/s sequential write... But shouldn't be the case for KVM editions.

As to why your storage device

It's not a hardware issue!.. Your running in a virtual environment!.. It's a device driver issue, and it's because you're using the virtio_blk device driver; just run this command to attest for that:

Code: (Select All)

lsmod | grep virt

If you happened to be used the virtio_scsi version, your virtual disk would have the 'S' prefix instead of 'V'. But it's the deploy-er decision not ours.

Anyway, I think you're onto something here, and I'll comment further one you update the miss-hap.

Thanks for the information HR and fChk. I've updated the OP with the results with the LVM root partition "/dev/mapper/centos-root" and I think it should be fine now.

I wasn't inside the /tmp folder while doing the tests though; it's just that I used "/dev/loop0" to do the tests when I din't find "/dev/sda".

Sorry!.. but I still can't get my head around those results!

I would have preferred that you also post the commands corresponding to those output. It's always an uncomfortable guessing game when we want to interpret outputs of missing commands.

What's needed is the benchmarking of the virtual disk as a whole (ie /dev/vda); bypassing the file-system entirely:

Code: (Select All)

# Disk seq.read Speed (Cached)

hdparm -Tt /dev/vda



# Disk seq.read Speed (Direct)

hdparm -Tt --direct /dev/vda



# Disk Seek Rate:

ioping -R /dev/vda



# Disk Sequential Speed:

ioping -RL /dev/vda

As for dd, please run the io section of your script inside your sudoer home directory.

The values in the OP are too high to be credible for a Virmach KVM VPS. If the results of the commands I posted above proved otherwise, then you'll have won the JACKPOT indeed, storage performance-wise !..

What makes me believe that's not the case is this:

Code: (Select All)

--- /dev/mapper/centos-root: (block device 78 GiB) ioping statistics ---

3.53 k requests completed in 2.76 s, 882.8 MiB read, 1.28 k iops, 320.1 MiB/s

generated 3.53 k requests in 3.00 s, 883 MiB, 1.18 k iops, 294.3 MiB/s

min/avg/max/mdev = 311.7 us / 780.9 us / 16.3 ms / 963.3 us

A rate of 294.3 MiB/s in disk sequential read is much more credible frankly!

VPS 9 (Atlanta) - My Dream VPS!

Presented by @sohamb03 ; Directed by VirMach

Hello everyone!

This is none other than me to present a review on VPS 9 (Atlanta), belonging to the present mega-VPS group of Post4VPS, both in specifications and stock.

THE STORY

I won this VPS on the 7th of September, 2019. I'd casually submitted a VPS request to be honest, I'd never really thought of winning this amazing VPS at the end of the Giveaway. When the Giveaway was on-going, little did I realize that this VPS, which has been an all-time favorite at Post4VPS would be mine. My spirits were really dampened when I came to know that a lot of candidates had applied, and only three of them remaining in stock with about 5 canditates already in the race, I'd assumed I wasn't going to succeed this time.

Destiny was otherwise. On the 6th of September, 2019, @deanhills informed me (oh BTW I has initially applied for the Seattle location) that Seattle was the only location of VirMach VPSes that had a negative VPS review. He suggested that I could choose Atlanta, as Arsal has recently dropped it. I'm glad he made the suggestion that day, and today I take this opportunity to thank him a ton for the suggestion. Arsal is to be thanked too, for dropping this one, to my advantage.

The very next day, came the best news. I did win the VPS and my happiness knew no bounds. Thanks to @Dynamo for organizing this forum, that brought us all together. I must say I've made great friends here, and this VPS - VPS 9, is one which I could've otherwise never afforded myself. This VPS played a great role in improving my skills in the Linux Administration, and it is through this VPS, that I learnt a lot of things.

Agreed that this VPS did cause a lot of trouble during the OVZ to KVM migration, I've very little to complain about as these were very petty problems compared to the great benefit I derive out of this VPS. (FUN FACT: I'd 6 OS re-installations on this VPS, basically I troubled Dean a lot. )

It's been 9 long months that I've been the holder of this VPS, and its time I justify the VPS and convey my regards and thanks to VirMach, through the medium of this review. Enjoy reading further!

STORAGE BENCHMARK

I've 70GB of storage on my VPS. In VPS 9, you can choose in multiples of 5, and I didn't need much storage till now, but I'll need more soon with another OS re-installation.

Code: (Select All)
Filesystem Size Used Avail Use% Mounted on devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 64M 3.8G 2% /dev/shm tmpfs 3.9G 384M 3.5G 10% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/mapper/centos-root 47G 17G 30G 36% / /dev/loop0 1.5G 9.0M 1.4G 1% /tmp /dev/mapper/centos-home 23G 1.1G 22G 5% /home /dev/vda1 1014M 228M 787M 23% /boot tmpfs 783M 4.0K 783M 1% /run/user/0 tmpfs 783M 0 783M 0% /run/user/5003

For the boot time: (Actually I've a GUI - XFCE - running on the VPS; not sure why it didn't show up )

Code: (Select All)
Startup finished in 861ms (kernel) + 2.761s (initrd) + 12.130s (userspace) = 15.753s

Although, the boot time is pretty cool.

Now for the tests, directly from the Benchmarking Script:

Which is a remarkable performance!

This is the disk-speed-beta.sh script, not yet merged into the benchmarking script but just a confirmation of the above results plus the cached mode.

(PS: Here I encountered a strange problem. I'm not an expert at all this; since I don't deal with hardware at all. For some reason, my system seems to be missing "/dev/sda" and I've the least idea why, so I performed the upcoming tests on "/dev/loop0". No idea if that makes a difference but nevermind. If I were to make a wild guess, I got CentOS 7 installed from ISO since I needed the default partitions for some purpose ... maybe that's why.)

Download speed may not be great, but good enough for my purpose.

USAGE

Here's the most important part - the use case of the VPS lol.

I presently have CyberPanel running on he VPS - and two websites including my speedtest server being powered by the same. Also, I give free web hosting to one of my friend.

I've 6 Discord Bots running on that VPS (3 for me and 3 for yet another friend). All of them are coded in Python, and the server handles the load quite well. Not using much RAM and CPU honestly, except a few occasional spikes.

A GUI - XFCE - is running on the VPS. It's the lightest GUI available (cuz I've previously faced problems with GNOME and MATE).

Development and testing of my scripts.

A private OpenVPN server for myself.

I'd installed Pterodactyl panel initially on the VPS; but on noticing that it consumes a lot of resources and conflicts with other applications on my VPS, I wiped it off.

I always keep aside little resources (which is why the free space) for testing new stuff, panels and beta testing of other applications.

SUMMARY

Let's sum up this review.

1. I'm extremely satisfied with the VPS ... it's perfect for my needs and use-case. I do not regret keeping a considerable space empty cuz they get filled and wiped occasionally.

2. As we all know, VPS 9 doesn't have a control panel, but honestly I never felt the need of having one. Dean and HR have been very active at support and my level of satisfaction knows no bounds.

Again, a huge thanks to VirMach and Post4VPS, for this amazing VPS. Also, thanks for taking time to read this review, dear readers. Although I've tried to keep this review as descriptive as possible, any feedback, suggestions are welcome. I'll try my best to include them as soon as possible.

Regards,

Amazing and insanely detailed review you got there! Looks beautiful too with the way you formatted it! I enjoyed reading every little character on your review, so kudos for that!

Since we both have VPS 9, just different locations, the specs a vert identical! However performance wise, something just isn’t right on my end (more on that below).

It specially caught my attention that you mentioned that Deanhills informed you that the previous holder of VPS 9 Seattle had negative feedback on it (never knew that to be honest). That, if anyone here doesn’t already know, is the same VPS i had currently. And apart from a ton of miscommunication that went on almost every time i tried to ask the staff to do me something for it (not really the VPSs fault)... I haven’t had much negative to say about it except for ONE thing that I haven’t mentioned before (simply because I don’t want to trouble the admins more than I already have... so I learned to live with it):

And that one thing is that it tends to be quite slow in tasks such as establishing the SSH connection and logging in, along with running tasks as such updating dependencies and upgrading the packages. At first (for several months for a matter of fact) I thought that was normal... however, based on feedback i got from several VPS 9 holders, I’m the only one experiencing this. I couldn’t narrow the issue dowm however... network speeds are at a comfortable 800-900Mbps, and disk I/O speeds have been very inconsistent, but the max I’ve seen was around 500MBps, which is quite good (interesting to see that your VPS has almost double that... but I doubt that this could be the issue since ~500MBps I/O speeds is still blazing fast). But anyways, it’s not that huge of a deal as I’ve, just like I’ve mentioned previously, learned to live with it.

Thank you Post4VPS and VirMach for providing me with VPS9! But now it’s time to say farewell due to my studies.

Thanks @ikk157. Well, it turns out that what Dean had warned me against Seattle is correct. Why don't you open a support ticket in the private VPS support section? I'm sure Dean can contact VirMach regarding the performance of the VPS and get it sorted.

@fChk Done updated the thread again with the new results and also, I included the commands I used for every test. At first I skipped it cuz I thought it'd be making the thread unnecessarily longer but nevertheless. I've taken care of the following:

Benchmarking of the virtual disk has been done as a whole.
dd outputs have been run the sudoers home directory.

Also, it seems only the sequential rate dropped by a bit, but it's still good as far as I understand.

BTW, here's something I wanted to ask. As I said, I'm more into software than hardware, hence, I can't make out why the sequential rate is so high on /tmp. Can you please explain to me?

Code: (Select All)

The reason why I haven’t already done that is because I’ve already bothered him enough. I feel like I’m the most troubling VPS holder over here considering that no one else is as demanding as I am.

That’s exactly why I don’t want to trouble him any more regarding anything. Even I wouldn’t appreciate someone constantly asking me to look into stuff.

Not to mention that, just like what Dynamo has told me when I contacted him about something completely different, VirMach already does so much for post4vps. We don’t want to trouble them with anything. And I absolutely agree with what Dynamo said!

Also, complaining about something that’s completely free is just bad. VirMach is after all providing this VPS completely free of cost. And the post4vps staff members are voluntarily dedicating some of their precious time into into making all of this possible! The last thing I’d want is to be a pain in the butt for any of them.

Thank you Post4VPS and VirMach for providing me with VPS9! But now it’s time to say farewell due to my studies.

@ikk157 The VPS 9 Seattle review was dated 2018 when we still were on OpenVZ. Seattle and Chicago VPS got upgraded to KVM towards end of 2019 (think it was October) as the first VPSs to be upgraded to KVM and the upgrades were very high quality, much higher quality than the other locations whose upgrades possibly got automated. At any rate, possibly due to expert network configuration with the KVM upgrade Seattle VPS turned into a much more powerful VPS.

Would be interesting if you could make a comparison of the stats quoted in the 2018 review and your experience with the KVM version of the same VPS.

I absolutely agree, just looking at that older review you linked (thanks for the link!), I can already see a lot of improvements CPU-wise and disk speeds as well!

My existing review serves as a great source of KVM benchmarks which will allow people to compare it to the previous OVZ review you linked. I’ll go ahead and post an update on my existing review with my overall experience now that I’ve been the proud holder of VPS 9 Seattle for almost 8 months!
