Low hashrate on Xeon E5-2620 #515

Open jmusac opened 6 years ago

jmusac commented 6 years ago

Hi,

I have system with 2 x Xeon E5-2620. On that system created Virtual machine and assigned 22 processor cores to it. I'm getting low hashrate on all processor cores. About 10 H/s. According to monerobenchmark site that should be about 30-ish H/s per core or total about 450 H/s per this processor.

The same thing happens on Windows Virtual machine or debian virtual machine. I attached picture below.

If you do not set the CPU type for the VM to "native" or "passthrough" then it will not have all the CPU features ("Qemu CPU" is not a Xeon...)

Your hashrates seem to match a non-AES processor, therefore I suspect the AES feature is not being provided to the VM.

I run my miners directly on the Proxmox installation, using a VM is kind of like putting on two pairs of socks - it works but why, it is never faster, brings problems, causes blisters. :)
