Hello Alan,
I am now running quite nicely your latest stuff..;-) It feels GREAT. But the throughput at least on my system is somewhat lower than with my latest -aa VM (vm_25) kernel 2.4.18-pre8-K3-VM-24-preempt-lock.
I am going to compare "your" version against 2.4.19-pre2 vm_28 read-latency2 O(1)-K3 (the hardest part) preempt + lock-break (got that but not Ingo's stuff then) 2.4.18.pending ReiserFS stuff
All OOM problems are fixed with vm_28 for me. I've checked it with and without swap. With former versions some system tasks (smpppd), kdeinit and desktop processes (xperfmon++, kpanel, kmail, kalarm, etc.) were falsely killed.
With 2.4.19-pre2-ac2 + pre and without swap (I disabled it before running the "test" prog) kswapd (?) goes into 20~25% system time usage and the whole system gets unusable. I had to reboot...
X have to be reniced -10 to get smooth mouse movement under both kernels (Ingo's part) during compilations (bzlilo).
Regards, Dieter
BTW Some numbers will follow when I get O(1) + preempt going with 2.4.19-pre2 + vm_28.
