    Unhappy 2.4 vs. 2.6--2.6 extremely slow for everything


    I have a P4 3GHz PC and no matter what distro I install, if i use a 2.4 kernel, the machine runs fine, but if i use a 2.6 kernel, the machine is incredibly slow with everything from booting, to normal use, like opening and switching b/w applications, to shutting down and logging on. I've tried Centos, Fedora, Ubuntu, and Debian.

    Any insight as to what may be the problem?

    Is it a pre-compiled kernel or did you tweak it yourself?

    I did not tweak it, I just used the installation provided by the distro.

    If you want better performance, you should compile the kernel from scratch. You can get a copy at http://kernel.org, and some instructions are here.
