SubjectProcess Creation Speed
Date
Why does creating and then terminating a process in GNU/Linux take about 6.3
ms on a Prestonia-2.2? I observe basically the same thing on a PIII-600.

I'm pretty sure both systems run 2.4.x kernels. Does this suck less under
2.6.x? Not sucking at all would mean about 100 microseconds to me. I don't
understand why it doesn't scale with processor speed. Does this interact
with the length of a timeslice?

It matters to me because the Common Gateway Interface spawns and destroys a
process to handle each request, and I wish it were just fast, rather than
having to use FastCGI.

A fair amount of Googling and RTFFAQ didn't answer this.
