I would like to know interrupt latency of Xeon E5504 measured from the time of external interrupt
to the time when an application in CPU detects the interrupt (maybe through Interrupt Service Routine).
I've got the following paper from Intel web site (under 5500 series page).
According to the paper, it seems that Fig 8 (page 18) shows an approximate interrupt latency.
But I'm not sure if I can count on those numbers for my purpose.
Any comments would be appreciated!
