![]() ![]() You have different guest os/kernel/config You can still have low utilization but an avx benchmark will tank It highly depends on what the vms workload is on how much it will consume the processors resources.įor example, a processor has limited amount of avx instructions it can execute. Please do not do benchmarks on loaded hosts. The only difference is that the average CPU usage of the node with 3800X is 10%. Even the multicore performance of the Ryzen 7 5800X VMs are inferior to the 3800X. I also reduced the amount of cores in some VMs to try to improve performance, but it had no effect. ![]() On the Ryzen 7 3800X node, I put more cores in some VMs for testing, and in geekbench the result is still the best possible. (Lower performance is to be expected because there were 18 VMs connected at the time of the test, but I expected lower performance only in multicore and not in singlecore, maybe I was wrong).īut the VM still gets about 20% less than the singlecore power of the node. The node's singlecore test did not look so good compared to the average of other Ryzen 7 5800X, about 10% lower. I tried the test on a VM and on node to check the singlecore usage.īefore starting the test, the node had 20% average total CPU usage. ![]()
