Interrupt Latency.

Could anyone give me a clue what the normal interrupt latency is under Linux
2.0 or 2.1 on a Pentium.

That is, if I put in a driver which responds to an interrupt simply by
waggling an output bit on the parallel port or something similar, what kind of
time delay will I see if I put a scope on it?

Thanks.
