    Good Day,

        I was wondering if anyone on the list has noticed any performance
    issues with JFS2 and AIX 5.2 ML-1, most notably memory issues. The
    reason I say this is because when I looked at one of my systems this
    morning, it was using 99% of it's memory and starting to swap like crazy
    according to nmon64. TSM was backing up a test filesystem at the time,
    so I killed the tsm process, and unmounted the jfs2 filesystem and poof!
    my memory usage went down to 31.5 percent while the filesystem was being
    unmounted. Granted, this is a huge filesystem in the 200 GB range, but
    should it really eat up THAT much memory?

    TIA,

    Anthony
