    SubjectProblems with too much memory (?)

    This still may be hw problem, but aybe it is not.
    My machine is 486DX2/80, 128kb level 2 cache (stolen from one 386 :-),
    20MB ram (16M+4M). It compiles kernel about 32 minutes.

    When I removed 4MB SIMM, compilation time went down to 22 minutes. I
    thought that it is hardware problem, but I wanted to investigate it more.
    So I put memory back and limited memory to 16M (mem=16M). Compile time
    stayed at about 22 minutes.

    So I suspect linux tfor 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?]

    This is my little buggy signature... Pavel
