eribob Posted May 24, 2020 Share Posted May 24, 2020 Hi! I finally built my 3950x unraid system and I am very happy with the performance increase so far! I have done some benchmarks today with my windows VM, and I would just like to ask if my numbers are to be expected or if there are tweaks to the xml that could improve performance? Precision boost overdrive is turned on in the BIOS. Cooling the cpu with noctua NH-D15. To test, I assigned all cores to one windows VM and shut down all dockers and other VM:s. It resulted in: Cinebench R20: 8600-8700 multi-core Geekbench 5 CPU: 1186 single-core, 11470 multi-core For actual use I have isolated the last 8 cpu:s (8-15, 24-31) and gave them to the VM along with 32GB of RAM. This resulted in: Cinebench R20: 4552 multi-core Bare metal performance seem to be around 9100p in CB20 and 14300 in geekbench, meaning I get around 5% decreased performance in CB20 and 20% in geekbench. Is this to be expected from the virtualization? Quote Link to comment
