-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1I've heard that SELinux has produced benchmarks such as 7% increased CPU load. Is this true and current? Is it dependent on policy? What is the policy lookup complexity ( O(1), O(n), O(nlogn)...)? Are there other places where a bottleneck may exist aside from gruffing with the policy? Isn't the policy actually in xattrs so it's O(1)? Where else would an overhead that big come from aside from a lookup in a table? ....Why is the sky blue? Why do you have a mustach? Why doesn't mommy have one? Does she shave it? At any rate, my personal end goal is a secure high-performance operating system, as user friendly as Ubuntu, Mandriva, or Win----. To this end, I'm (still; a lot of you have seen me before) evaluating the performance hit of various user and kernel security enhancements like PaX, ProPolice, various OpenWall/GrSecurity niceness that needs to be divided out, and of course LSM/SELinux. Also wondering about that PHKMalloc thing on openbsd; is it really all that, is it junk, how's it compare to the recent ptmalloc work, and can it run on Linux for direct benching . . . but that's off topic.- -- All content of all messages exchanged herein are left in the Public Domain, unless otherwise explicitly stated.
