I do use the 2.4.18 patch too. > Kernel 2.4.18 + rtl3.1 with above patch shows 400 to 500 microsec > latency, which is unexpectedly large, with examples/measurement > test-program. I don't see this behaviour: 80% of the measured samples have a 10-14 microsec latency. But I do see sometimes (seems to be when I overload the Linux kernel with network card interrupts...) the latency going as bad as 300 microseconds. I don't know if this value is normal (I suppose it's not) and I don't know if it's caused by the 2.4.18 port (didn't test the official 2.4.4 version...).
