It seems that the version of O(1) scheduler on 2.4.19-pre10-ac2 is not
perfect (see below), but I asked because it gave me overall performance
gains, specially in multithreading programs (and now I'm going to try
with ngpt 2.00). At least that is the first impression, I'm trying it
for a few days.

I said "not perfect" because a rather non-important benchmarking called
quake 3 seens a lot worse in pre10-ac2 with preemptive patches when
compared against -pre10 with preemptive patches: sound and screen popped
sometimes, like if there was a background task borrowing some cpu, which
was not the case, I mean, no other background tasks compared with
testing against -pre10. That was the only exception to the above
paragraph that I can remember of.

Anyway, that "benchmarking tool" isn't rather serious and I'm no
benchmarking expert :-)

Thank you,

Alexandre
