I have a P-III 933/133 with the Apollo Pro chipset from VIA + 133 MHz SDRAM,
and a G400 DH MAX. I don't have any RTL or RTAI kernels on that machine,
though...
However, I'm using a 2.4.0-test10 kernel with the lowlatency patch, and it
performs excellent under X stress. I've benchmarked it WRT latency, and there
are no peaks above the 1 ms limit, IIRC; certainly nothing near the tens of ms
you've observed.
Now, I *think* I'm speaking about 3.3.6 above (one definite sign of having too
much going on...) - I don't think I've run the benchmark after installing
4.0.1, so I'll try this soon. (I encountered serious problems with disk acess
related latencies, and have since not had time to deal with it, so that's
basically why I haven't bothered testing seriously with different X versions
yet.)
