Context switch spec?

Can anyone tell me the current spec for the bounded
context switch time (not interrupt latency) in RTP on x86 at a particular
clock frequency?

Also, does anyone know if the Mach kernel in Darwin has a
bounded context switch time, and if so what it is?

I doubt you will get an answer, only solution is to measure it yourself on
your hardware. There is to much variables involved to come up with a number
like that, cache size, bus speed, memory type, processor type (P3/P4/K7/K8)
etc.
