    Add silent and cool operation and it's by far the best upgrade I've ever done!
    Agreed. My laptop runs so cool that the fan hardly ever turns on.

    I laptop already boots in about 20 second on Karmic so it will be very exciting to see how fast Lucid goes.

    I ran Karmic from the first alpha and had few problem (except with the change to the new version of GRUB) till I got to the betas. Then lots of things starting going wrong, I was getting maybe 5 crashes a day from various programs.

      Two questions that come to mind.

      What about KDE 4.4, is that about the same speed as Gnome.

      And what really kills me with my laptop is how long it takes to turn off with 9.10. When you in a hurry to go somewhere those 20 seconds it takes to power down feels like an hour.

        Boot performance

        Bootcharts would be more interesting with comparison of ubuntu9.10+ureadahead update against ubuntu 10.04.(Which made huge difference for HDDs). Moreover 9.10 bootchart was counted to X start + 45 sek, and its counted different on Lucid so I don't think that you should compare where the chart ends. It would make more sense to compare where simmilar processes ended loading.

          KDE cannot be as fast as Gnome, since it has so many more features. Still, on a cheap laptop I bought last summer (~500€, onboard intel video) I could not tell the difference.

          About the shutdown issue, maybe hibernate will do the trick?

            I've installed KDE 4.4 on VirtualBox and it feels rather slow compared to Gnome 2.28 on the same configuration. However, someone mentioned that KDE 4.4 flies with the proper drivers (radeon on Lucid, IIRC).

            This could be a problem with your configuration, maybe a daemon that refuses to die or a hard disk that is slow to unmount (maybe it is turned off and needs to be turned on before it is finally unmounted? I've seen this happen before). I have three Karmic systems and all shut down in less than 5 seconds.

              Still, I wonder what's the impact of moving installing kernel 2.6.33.
              Why use 2.6.33 if you use a SSD? Is that what you're asking? The 2.6.32 doesn't support TRIM and/or isn't activated so it's best to use 2.6.33 kernel if you are using a SSD which supports TRIM.

              I was looking into buying a SSD for my desktop (geez, I wish I owned a modern laptop now... an SSD seems like a required purchase with one now... talk about best of all worlds!). But, the Linux support in TRIM is in infancy right now. Not really stable compared to in Windows. I still want to get one and I'd just use it in Windows and the old/current HDD for my Linux.

                Lucid is using 2.6.32. I was just wondering if using 2.6.33 instead does anything for performance.

                As for the other thing, I won't pay more than $1/GB. Nor do I afford to. So one more thing for me to worry about

                  I read that TRIM has been supported since .28, but of course there's supported and supported well. If it was disabled that makes me wonder if there was a problem with the support. The only drives out I can see that support TRIM are really expensive any way.
