you can't possibly get reliable latency of around 3ms without a kernel
patch. if reliable latency performance matters, then any figure less
than 100ms requires a kernel patch. i don't know why you'd want to use
2.4.8 - the VM system is fundamentally broken until about 2.4.15 or
so. you have a choice of either the andrew morton "lowish" patches or
the preemptive kernel patch from robert love and friends.
