please advice is there a way to check
that RAID1 read speed can be a bottleneck ?
like 3 VMs are more than NVME Raid can give
and that's why VMs are slow in responce

@gudge25 i disabled TCP Offload checksum errors

ethtool -K eth0 tx off rx off

but no luck

@gudge25 Strange is that

Host + 3 VMS started to use more CPU on exactly the same day (time)

Host:

VM1

VM2

VM3

@gudge25 POOL

@DustinB
Storage

Server itself

@olivierlambert my bad sorry
i have a server with 3 VMs on it
from a prev week without any reason CPU utilization doubles
and I noticed even on reboot VM Grub loads with a delay

so I'm wondering is there a way to check maybe one or all VMs started overload server

need advice how I can identify that
Regards
