High %RDY time

[as900w]

I have a ESXi server that as a hypervisor for XenDesktop, and running virtual desktop.

When the virtual desktop has been running for a while, it is running to be very slow.

After reboot the virtual desktop that all ok.

The %RDY of desktop time is high by esxtop check. such as 16%,18%，19%... some more than 25%.

But, the PCPU Used avg is 39%

What should I do?

Hi @as900w 

If this field is larger than 10% it could mean that you have more requests for CPU processing than resources available.

%RDY time is the best indicator of possible CPU performance issues.

Check Lower the number of vCPUs 

Sometimes lowering number of vCPUs for particular machine will work
