SubjectRe: Problems with too much memory (?)

So I suspect linux for having problems with too much memory.

My linux is 2.1.35, slightly modified (PCspeaker, Hypertech cdrom,
Network block device, mingo's performance patch into sched.c).

30% difference is quite a big one, and I suspect problems somewhere
in mm / buffer code.

[BTW mingo's patch speeeded up my system by 30% some time ago - and
it was not still included in linux kernel. Why? Could someone
compare 2.1.35's performance with 2.0.29's?]

I have made extensive changes to the inode subsystem, it may fix the
problems you are seeing. So if Linus sticks what I sent him into
2.1.37 you can test things out when he releases it.

Yow! 11.26 MB/s remote host TCP bandwidth & ////
199 usec remote TCP latency over 100Mb/s ////
ethernet. Beat that! ////
