    http://bugme.osdl.org/show_bug.cgi?id=898

    Summary: Very HIGH File & VM system latencies and system stop
    responding while extracting big tar archive file.
    Kernel Version: 2.5.75
    Status: NEW
    Severity: high
    Owner: bugme-janitors@lists.osdl.org
    Submitter: bakhtiar@softhome.net


    Distribution:Slackware v7.1 : glibc v2.1.3
    Hardware Environment: P!!! 550 MHz, 256 MB RAM. HP Brio BA600

    Problem Description:
    1) lmbench v3.0 indicates VERY slow file handling since v2.5.74. I am using
    reiserfs as a default FS.

    File & VM system latencies in microseconds - smaller is better

    2) System stop responding while extracting big tar.bz2 archive file; example;
    MozillaFirebird.tar.bz2 (about 32MB). ps indicates that sistem stuck at tar
    process (pid 3607)
