    Re: Improve performance in Ubuntu

    I just removed readahead as well as preload from my Kubuntu 6.10 box. Strangely, this reduced my boottime from 1:11 with readahead enabled to 0:51 without it.

    So I guess Edgy with Upstart doesn't benefit by readahead. On the other hand, It could be that my box doesn't have enough I/O speed to make readahead worthwile. I run Kubuntu on a AMD Athlon 1.2 GHz processor, with 786 MB of RAM.

    Let's just hope the utter silence after this post isn't an indication that Seisen destroyed his system with these tweaks.

    Thanks so much, I never knew it set the RAM usage so low... Wow.

    This was very helpful, love this website.

    I think the tweak is not so great:

    Seperate question - why does doing this cause amaroK to not slow down the system? Won't it still have to install KDE packages?
    Hi, I have trawled Google to no avail. I am running Intel Centrino Duo. Which kernel should I be installing?
    Currently running Hardy 2.6.24-19-generic


    Thanks.
