Hmm, So I wonder how to reverse this to judge what CPU budget is necessary - or rather what device should be used.

 

Assuming that my average for iRule is 3.5M then trying to handle 2k CPS I need budget of 7000 000 000 - is that correct?

 

Then I am not sure how it applies to VE with for example 4 vCPU - if for example cpu is reported as 2GHz considering that there are 4 vCPUs is my rough budget 8000 000 000? So iRule will most probably kill VE?
