I’m running KVM node backed by 2 SATA disk in RAID1 ( HP P400 ). I did some disk benchmarks and got some reasonable results as per my knowledge.

slow command output

I attached a GIF image, is anyone can help me to resolve this delay ?

PS : I just found out that this only happening on Debian guest KVM's
