    While I think you couldn't be more wrong I'm not going to argue that topic....

    I am at least interested in hearing about the 'performance plummet.'
    I don't see any performance reports on my todo list but I am
    interested in banging on any that people report. Last performance
    thing I heard anything about was Ingo doing some profiling of of a
    network stack benchmark in which SELinux was eating a percent or two
    his time. I cut the SELinux performance penalty by about 50% on my
    systems in that benchmark. If others have complaints let me or the
    selinux list know....
