Hi

I have a 24 core Xeon 2620 with 2 processors and 128 Gb of run. The OS HD is a M.2 flash drive.

The CPU won't go higher than 5%, the memory is at 45% usage. But I'm seeing IO delays constantly averaging 5% with peaks higher than 20%.

Looking in the summary page of each VM I didn't any IO delay on them. How can I figure out the culprit ?

My version is updated with 6.4.9 and with the lastest linux core (5.4 if I remember correctly) that came out this week.

I'm newbie.

Thanks
