    SubjectRe: Scalability requirements for sysv ipc
    Hi all,

    I've revived my Dual-CPU Pentium III/850:
    I couldn't notice a scalability-problem (two cpus are around 190%, but
    just the normal performance of 2.6.25-rc3 is abyssimal, 55 to 60% slower
    than 2.6.18.8:

    psem 2.6.18 2.6.25 Diff [%]
    1 cpu 948.005 398.435 -57,97
    2 cpus 1.768.273 734.816 -58,44
    Scalability [%] 193,26 192,21

    pmsg 2.6.18 2.6.25 Diff [%]
    1 cpu 821.582 356.904 -56,56
    2 cpus 1.488.058 661.754 -55,53
    Scalability [%] 190,56 192,71

    Attached are the .config files and the individual results.
    Did I accidentially enable a scheduler debug option?
