Advice needed on servers (alien.top)

I currently have a 2 node proxmox cluster composed of PowerEdge R620

Node 1 has 2 x E5-2670 CPU and 128GB of RAM Node 2 has 2 x E5-2660 CPU and 128GB of RAM

I am and want to use these to host some Win2022 DC as well as some Ubuntu containers and servers (pihole, Zabbix, *arr). I also want to spin up VMs and/or containers to test new solutions and perfect my knowledge.

Should I upgrade the CPUs to 2690v2, 2695v2 or 2697v2 or should I look at other options to improve performances.

Electricity cost for running the servers is a non issue.

The console is laggish. I have just setup a Windows 2022 server 2 CPUs with 2 cores and 32GB of RAM

I've used the diskspd utility to do some benchmarks

-t4 - o32 -b4k -r4k -d120 -Sh -D -L -c5G

I've done tests by incrementing the -w parameter by 25 starting at 0

The results are as follow w0 CPU AVG 92.66% TOTAL READ IO/S 11649.49 AVG LAT 10.97

w25 CPU AVG 3.26% TOTAL READ IO/S 214.61 AVG LAT 425.091 WRITE IO/S 71.72 AVG LAT 522.129

w50 CPU AVG 37.05% TOTAL READ IO/S 130.02 AVG LAT 447.86 WRITE IO/S 130.29 AVG LAT 541.224

w75 CPU AVG 3.54% TOTAL READ IO./S 116.64 AVG LAT 248.616 WRITE IO/S 347.08 AVG LAT 285.8

w100 CPU AVG 33.62% WRITE IO/S 152.35 AVG LAT 838.956

The proxmox host has 2 ST600MM006 HDD (10K RPM) configured in Raid0 with a PercH710
