Introduction
VPS 5 is hosted by https://cobalthost.net/ and was given to me during the last VPS giveaway. It's located in Canada and uses VMWare as visualization technology, which offers great performance and flexibility. Specs seem fine, especially 50GB diskspace and unlimited traffic.
Specs in detail:
  • Disk Space 50 GB
  • RAM: 2 GB RAM
  • IP Addresses: 1x IPv4
  • Virtualization: VMWare
  • Monthly Traffic: Unlimited
  • Location:  Canada
  • Control Panel: Cobalt Panel
  • Connection: 100 MBit/s
Detailed Specs
The VPS has 2 Xeon Cores
sysctl hw.model
hw.model: Intel(R) Xeon(R) CPU           E5335  @ 2.00GHz
Xeon looks awesome on first glance, but if you look it up, it is a 9 year old CPU and that shows, as we will see in later benchmarks.

Installation
cobalthost is using their own Panel, which fulfills the basic needs, shows cpu/ram/hdd usage and offers the usual suspects like reboot/reinstall etc.
CPU Usage is always wrong in the panel, mobil version does not work. Installation works, which is most important.
One can choose to install on DC-2 or DC-3, since nowhere i can see the utilization of either node or see what hardware is in it it's is a gamble.
I first chose DC-3, which was a mistake. It is so slow that there can be only 2 reasons for it. a) it has like hundreds of VMs running, or b) the hw is dying (as in faulty), possible the hdds.
Booting a VM takes up to 5 minutes, installing ~30 minutes.
So i reinstalled on DC-2, which works better, boot and install times are normal. Installation went without issues. Their install script leaves a /bin/npasswd script back and a non working rc.local entry in case of debian. On FreeBSD i could not find any artifacts but 2 installed packages.
There is a slight installation bug with FreeBSD, which i already reported. (swap missing), also it installs on UFS2 instead of ZFS, which is a bummer but should do for most tasks.
One cool with with cobalthost is that you can have as many VPSs as you have resources for, so with 2 cores you can do 2 VPSs. Very cool.

Benchmark
Since i am running FreeBSD the usually FreeVPS benchmark script won't work, so i had to improvise and used unixbench.

Now that looks kind of horrible. As a small comparison a FreeBSD VM on an older core i3 under load in production had a Final Score of "231". FreeBSD VM in an older Xeon also in production with load on it did "362".

As you can see, it is worse than on a raspberry pi on sdcards, the 300ms+ peaks are especially bad.

Now that is also right up the raspberry pis disks speed as well. In all fairness, doing the test during different hour yield better results at around 12-30MB/s

Summary: Disk speeds and latency are bad.

That should be enough to get a rough idea and be able to compare with his/her own VPS/Desktop

Network:
Now the specs say 100mbit, but in reality it is connected with gbit, which is nice. Speeds inside Canada are good, ok to the USA and not so good to Europe but that was to be expected.

upload speeds are worse, why that may be, i think everyone can guess. Generally the speeds are good enough for any personal use, for me at least its enough.
My VPN does 15mbit (compressed) to my home link, which is enough for my VPN related activities. Also enough for mumble/teamspeak or a small private website.

VPS Usage
I mainly use it for playing around with Operatingsystems and run a mumble and an OpenVPN server, both private for myself. Maybe i'll use to backup some stuff, since the 50GB disk space is nice.

Reliability
Can not say much about that yet, for now it has been stable, if it ever goes down i will update this thread.

Conclussion
Well that is a mixed bag, it is very old, dying hardware and probably over sold into oblivion. So if you are looking for a VPS where you actually have to run something that needs power or disk speeds from this century you are out of luck. A quad core CPU for half their customers(DC-3 has 6 cores i think) is simply not enough, also the apparent lack of a storage for the VMs other than the included HDDs on the old server shows, very much so. If you are looking for a VPS to do some private stuff, test your code, learn linux, run some small daemons or anything similar like that it does its job, after all it's free and for free it's good, can't really complain. For anyone looking to invest their own money i would suggest to look for another hoster.

greetings

p.s. redid all test with debian, same result, does not seem to be OS related.

Didn't you have any lag-related issue?
Cobalt's hardware really sucks...they are so slow that a cPanel installation takes more than 1 hour.

As far as I know, they use Cloud At Cost's servers...

They do, i suspect they over sell the resources so much. 9 year old Xeon does not have to be bad, but when you put a gazillion VMs on it even the most up to date Xeon will crawl.

Well lag related issues, yes and no, I am from Europe, so some lag to half way around the globe is expected, nothing too bad so far.

Yes... you're right. [email protected] and vps-hosting.(vps-hosting also uses [email protected])

How good is Cobalt's compared towards [email protected]? I know that someone said that you can use [email protected] to setup VMs inside of one, what is this?

Haha, I tried myself. running openvz on my cloudatcost server. (You can add 3 additional IPs, so I use main IP for the VM, but then I used the other 3 for the boxes. Quite funny to try out, but the quality sucks...

Do you mean nested visualization? Running vmware inside vmware?

Well, I mean someone mentioned that Cobalt does that. Uses a VM to hosts many other VMs on some doubtfull hardware, would that just affect speed and stability especially if its oversold as it is?

Could be, but i doubt it, since it does not make sense for them other than being even slower. Would only make sense if they sold vmware hosts, which they don't.

Edit:
Looked it up, the Xeon does not support it. So no, they are not doing it. I think they are just putting to many VMs on their 2 hosts. Plus the TE Mining they offer on top does not make it any better.
