Hi Scott,

Just to clarify, the original issue for creating this thread was investigating increases in CPU and interrupts / context switching that occurred during non-peak traffic. Now, however, our graphs are unremarkable. We're barely using any CPU ( <8% ) and the interruptes / context swtiching graphs don't show any oddities, yet server response times can be 30s+. It's confusing because the codebase is the same we had run for a week with much higher traffic without problem.
