In fact, it will actually slow the overall performence of the machine - hence me stating it should be left out of the more 'server' type kernels, but it as it is more responsive, it makes your system 'feel' faster, which, as a desktop user, is very beneficial. It basically decides which processes should get hoe much cpu time, where the linux kernel just normally divides it evenly (excusing priorities and i/o etc). As mandrake is aimed quite heavily at the desktop market (and i think is the best desktop OS i have ever used, although i havent tried OS X yet) this would benefit a great many users. I dont know if it can be copmiled as a module or not (i very much doubt it) but if this is the case,. i really would like it available as at least an option. Ive heard nothing but good things from people i know who use it, but i cant get the bloody stock mandrake kernels to compile (laziness) so i would really like someone else to do it for me ;) Tom - -- Tom Tomahawk Badran Department of Computing, Imperial College - --- PGP Key available from certserver.pgp.com -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8GUVDXCpWOla2mCcRAusIAJ0RpbWfk7+2Z4dqEroePNn39YVe1QCfTQxO VItg7/QXaiFuIRaAnlRhI8k= =QhkI -END PGP SIGNATURE-
