I was planning to do a meta-review of Virmach VPS-9 offerings -especially CPU wise- (a review of reviews), thus when I was going through the available threads on the subject, it appeared that @ikk157 was the only one who did run a Unixbench test :-)

Not only that, he did it in double-test mode!.. Kudos! and +1Rep for your courage :-)

Did you know that you most probably broke Virmarsh's ACCEPTABLE USAGE POLICY while doing it ? Both the high CPU and high load clauses:


I knew that for a fact because I was planning to run both the simple and double tests my self on the Phoenix-based VPS, but ended up doing the simple test only as it was the only one who can finish within Virmarch's rules, ie a load of 6.18 (1') 3.65 (5') 1.88 (15') and a CPU usage of 56% for most of the test duration and ending at 95.83% .

For the meta-review thing I did cancel it as there is not enough data in the published reviews for KVM-VPS-9 while others are still missing!

You can still use it in its trial mode-like everybody I would guess and it's more than enough. By the way, it doesn't abuse the CPU the way UnixBench does.



The “noisy neighbours” effect can still be felt within KVM's VMs; it shows up CPU-wise in the steal time statistic when querying your CPU usage.

When the steal time gets above 10%, your vCPU's performance drop as it's struggling to get its fair share of the real CPU from the hypervisor.

Container's VM (like OVZ) vCPU performance suffers most from the IOWait time statistic which can jump to levels above 30% making everything crawl to a halt.

It's all relative, and the main culprit in both cases is usually the overselling of servers' resources.

VirMach’s High CPU policy was back when the VPSs were on OVZ6. Since with OVZ, if you burst into a significantly high CPU usage you will affect your “neighbors”.

With KVM, on the other hand, it doesn’t really affect your neighbors much at all (sure, just like you’ve described, there is still a minor effect).

But again, the benchmark only ran for an extremely short amount of time so things should be fine. 

Would love to have a clarification regarding high CPU usage from an admin now that VPS 9 is a KVM.

As for Unixbench, thank you very much for your great comment! I wanted to avoid Geekbench altogether as the trial mode is not as in depth... Unixbench should do the trick.

Awesome review!
About the speedtest i think that you can open a topic for it but for my side i see it acceptable.

I don’t think the admins can really do anything regarding the low network speeds (for a matter of fact, I noticed that they’ve actually worsened now).

I’ve already bothered the admins enough and this just isn’t something I’d want to have them spend time on investigating... not to mention that all of this is free so we really don’t have the right to complain!

Update regarding the network speed on my VPS 9:

When running speedtest-cli, I get the following results:

Download: 873.11 Mbit/s
Upload: 1051.91 Mbit/s

As you can see, the network speeds here are excellent.

However, when actually downloading something (let’s say for example when running apt upgrade), it seems to struggle!

Even connecting to it through ssh takes longer than any of the other VPSs I’ve used.

I’m starting to suspect that the SSD is the bottleneck here, not the network speed. I’m not very sure though.
