    i have 384MB's ram on the 2 machines i've tried this on. that's the least amount on any of my machines. is that sufficient?

    That should be sufficient, yes.

    According to bootchart, the boot-time went from 35 seconds to 33 seconds

    Probably it can't be faster than that on my pc

    Re: TIP: Improve bootup speed by reprofiling bootup

    I have a question jdong...

    I had a look in my /etc/readahead folder.It also contains a file titled "desktop".

    Does the profile command generate this file as well?If not how is this file generated and is it possible to "reprofile" it for a boost?

    The "desktop" file is only generated/used for LTSP/Edubuntu setups, where /usr and /var are on different partitions. If you're looking to accelerate GNOME/KDE or another application's startup via readahead, sadly this is not supported. In fact, I'm not sure... we might already be using the readahead technique to its full potential

    An update to the HOWTO, I have added a Bonus Hack section that has readahead run in the foreground to further minimize disk seeking. This has proven very successful on my systems.
