CPU speed problem

[charles.gauthier at iit.nrc.ca (Charles-Antoine Gauthier)]

Hum... where to start... So many possibilities...

I would first assume a critical race, given that the problem is related
to the speed of the CPU relative to absolute time or to network speed.
But I would look for easier sources of problems first, such as a
mis-configured driver, hardwre differences, etc. Once you have
eliminated these, then go look for a critical race problem. Critical
races probably the most difficult bugs to find, and it will probably
take you a long time to find it. Hence, don't start with that until you
have eliminated all other possible sources for the problem.
