Hello,
How can I correctly check KVM guests' cpu performance in the proxmox environment?
I suspect that my VM's (windows guests) have much lower cpu performance than identical physical machines.
I measured the cpu performance with the built-in benchmark tool of 7zip archiver (one thread). The test was run under windows 7 guest (2 core, 2 cpu , 2GB RAM). The host server has 2 X Intel Xeon CPU E6510 (4 cores each with HT). All other VM's were powered off during testing.
The result (common rating) is 1260 MIPS.
I compared it with my "working horse" on virtualbox (windows 7 - 1cpu, 3GB RAM) with the same settings of 7zip archiver. The host machine has Intel Core i5 (4 cores).
It gave me the result (common rating) 2960 MIPS
Is it correct to measure the performance such way?
