The CPU performance of your VMs?

Lanz · 14 Oct 2016 at 12:16

Hi,

I've used Hyper Pi as a basic CPU test for years now, just to see how much raw CPU performance increase I get with each new esxi cluster compared to the previous gen.

At the moment, our newest clusters are using E5-2680 v3 @ 2.5ghz
The test takes 12 seconds to complete (1M, Normal, 1 Processor)
This is pretty much identical to the last gen from 4 years ago (original E5-2680 @ 2.7Ghz)

We still have a really old cluster that runs AMD 6136, and they are dreadful and it takes 33 seconds to complete.

I'd be interested to see some more results from others?

I7 5960X running 12 VM's

My 6136's take 29.344s, I got two quad cpu Dell R815's here.
Mine are used as hyper-v hosts and have plenty of RAM and IO so they are still really useful for dev boxes.

11.46 on my work desktop.

13.5 on our most heavily used e5-2430v2 & a paltry 29.8 on an ancient AMD 4180

19.4 on a bottom dollar azure vm, single cpu e5-2673v3.

Azure is interesting, what sort of price difference is there from that 20 sec VM to a 12 sec one you think?

I would say anything under 20 is fine for 90% of workloads.

10.63 on my home VM, Hyper-V on a i7 4770T. Remember to set HV hosts and VMs as high performance under power settings (on the host is a must, windows often leaves the cpu in a low state).

This, check the host is not in stupid power saving mode or balanced. VM's will sit at low cpu usage when doing heavy tasks.

LGA1366 L5630 CPU completes in 19.456s, its not a performance cpu by any stretch!

Next time we spin up a decent machine I'll do a test

24sec on my home desktop AMD 8320, safe to say that AMD's suck at pi benchmarks.
(the bigger picture is there pretty meaningless with real world cpu utilization anyhow so I dont feel bad)

I wouldn't say meaningless, activities that require encryption or compression run really slow on our AMD hosts - Large file backups takes 3 times as long, compared to Xeon when client-side compression is enabled, also our dev's are always complaining the java app performance on AMD. Be good to finally retire them off.

Is that E5 right? I would have thought it would have been much faster than my L5630 as its smaller node and slightly more efficient chip.

done some retesting, mostly around the same, did hit 17.4 on 1 test. Checked the vm settings and it is using 100% cpu

32.698 on my 10 year old Q6600 vm

10.715 on my desktop (i5 6600K)

10.73 on Windows 2012 VM running on a TS140 with E3-1226 v3 @3.30Ghz
20.74 on Windows 10 laptop with i7 4600U

12.5 seconds on the work desktop, running loads of applications.

Interesting comparison actually, I'll try it on a few boxes.
