Hi I'm using the preemptible kernel patch since 2.4.10 (no 2.4.11). And it makes a big difference on 486 with 12Megs of ram. I can't send you benchmarks (i don't have time for this but if you really want one ... it can be arranged :-)). But:
When I run a configure script I can actually see it running (without this patch it is very slow).
The coolest thing was that I could run Gnome and KDE (with loadavg of 4 and waiting 2 to 4 minutes for an application to start (because of ram I think)) something not possible without the preemtible kernel. I don't swear after them anyway.( I prefer fvwm)
Compilation is much faster (i'll make a benchmark compiling linux kernel -- i promise :-)) ).
The system is stable with high system loads. Now is kernel 2.4.12 and no problems at all.
Any chance to be in the main stable kernel ?
Bye
