Hi,

The issue is still there?

I have met an IO peformance issue recently and found that the count of the max fd for the Qemu/KVM was not bigger enough, the fd for Qemu/KVM was exhausted, the issue was solved after increasing the count of the max fd.

Did you check/test your network connection?
Do you have a fast network setup?

 I have a bond of two 10GB interfaces, with little use.
