It would be interesting to see where all your CPU time is being spent.
Correct - what do you need?
What benchmark are you using to do the random writes?
in KVM VM:
export DISK=/dev/vda
fio --filename=$DISK --direct=1 --rw=randwrite --bs=4k --size=200G
--numjobs=50 --runtime=90 --group_reporting --name=file1
