We are looking to get the most life out of our 6400's. In trending CPU usage using tmstat we see CPU around 55% - 60% during the business day.
We have plans to go to v10 but I wanted to know what a good top level benchmark is for CPU on the 6400 runing v9.x? I know it can use 100% but at what CPU level do you start seeing performance issue?
Knowing this will help in planning discussions and hopefully move the upgrade to v10 along quicker.
