Thanks for the answer. Do you know any tool/software to retrieve the average latency for a specific program on a specific platform. This is to modelize the application rate for data processing. 2014-06-19 22:16 GMT+02:00 <Valdis.Kletnieks@vt.edu>:

I could not find an answer yet. I've found that on latest kernel latency is on average around 3us with a max at 64us (I consider a moderate load). Is that correct ?
Depends on your hardware and system load. I'd hardly expect the same numbers from a busy Beaglebone or Raspberry Pi as from a idle high-end Intel i7 system....
(And things like processors that drop into sleep states when idle, with a latency hit to wake up, just add to the confusion....)
