Hi!
I am not a hacker but I read linux-kernel with great interest. (maybe when I grow up I become a kernel-hacker ;-) )

Yes! Interactive feel is more important for me than any benchmark result. As I always let play x11amp my favorite music in the background, it's also important that there are no breaks in the playback. So I booted my P166MMX with 128MB of RAM (SCSI-only) with mem=16M (your pre7-patch applied).
Here my subjective comment:
I am running X (fvwm2), netscape, 'find /' in an xterm, x11amp, kicq and writing this email with Pine.
There are no problems except the cursor jumps around when I am moving my mouse (I run X with a priority of -18, a good idea?).
X11amp (suid root, the readme says that it'll run in 'realtime-mode' then) randomly stops playing for a few milliseconds (while swapping).
Starting another xterm takes about 6 seconds. Console-switching is fast. No need to say that netscape reacts really slowly.
Network throughput is normal I think (~620 K/sec on a 10Mbit LAN, NE2000 compatible PCI-network card).
Attached is a ps snapshot of running processes.
Btw with 128MB RAM it's hardly possible to make x11amp pausing playback.
'free' says:
total used free shared buffers cached Mem: 14576 14192 384 6628 348 6724 -/+ buffers/cache: 7120 7456 Swap: 66460 23572 42888
I am very happy with current linux-kernels. No hang, no oops, no reboot, no problems (and never had). Really good work!
Greetings, Stefan
