CPU READY% & %CSTP

I need some clarification.

CPU READY - I have read 10% upper acceptable limit for cpu ready per cpu.

which is understandable

%CSTP should be less than 3% otherwise co-scheduler is having scheduling issues with vm's with multiple vcpu's.

This 3% is that per vcpu or total?

Below is a screenshot from ESXTOP i have highlighted 2 %CSTP figues.

Both these servers have multiple CPU's, so do i need to expand the vm and check %CSTP is less than 3% for each cpu or do i just look at the total like in the screenshot.

Image may be NSFW.
Clik here to view.

Any clarification would be helpful.

Thanks
