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....
