    Anyone else compiled the 3.0 kernel? While we're at it, what are your custom compile tips?

    I just set the processor type as Core 2, pick full pre-emption for low latency desktop, deselect amateur radio and embedded device support. What cool things can you do for a desktop kernel?

    Also, why is my memory showing as 2.8GB, when I have 3GB in the memory slots?

    I usually change the process scheduler frequency to 1000Hz as well as setting the processor features to match that of my CPU as well.

    Is 1000Hz not the default for 64-bit systems?

    I'm doing it almost everytime there is a new version in the git repo, but I'm still on rc7 now.

    You're using menuconfig, xconfig or standard distro .config file?

    I removed almost everything that is not used on my laptop from the config. It doesn't spped up the kernel, but it definitely does speed up compiling.

    3.0 is just a number, but I hope it will be an occasion to talk/write more about linux in different media.

    What does 'free' show as total RAM in the terminal?

    free shows this:

    I'm not really to clear on what all that means.

    I copy in the Ubuntu standard config from /boot and then open it with menuconfig, then make the few small changes I think will improve performance or reduce compile time.
