    This will be just as slow on a 600M filesystem...
    If there are a lot of files, it's going to take a rather
    long time to remove them. (Just try this under Windows:)

    On my 120mhz HP-UX system this same operation on the same set of files
    with the same model disk drive only takes a few seconds; whereas with
    my 200MHz PPro Linux system it takes five to ten times as long...

    Is it possible to optimize this?

    Fsck takes extremely long because it has to cross-reference
    all the inode and directory data...

    Yes, this is probably unavoidable...
