Ubuntu 9.10 boot time


I decided to finally clock the boot time on my installation of Ubuntu 9.10 (Karmic Koala). Total time from the GRUB menu to a fully loaded desktop is 31.5 seconds, including the time it took for me to choose my name and type in my password as fast as I could. Time from GRUB menu until login screen was about… I’m not too sure, but around 15-20 seconds.

Not bad! I would be interesting to hear others’ boot time!


Unnecessary database updating

I have a really old laptop that I put Ubuntu on. It used to have Xubuntu on it but even though Xfce is faster than GNOME, I like GNOME better.

There is a problem with a fresh install of Ubuntu however (and all other editions I assume), where there’s heavy unnecessary HDD activity, and the top utility reveals mlocate to be the perpetrator.

To disable mlocate running automatically, I just changed the permissions of /etc/cron.daily/mlocate to 644, by running:

$ sudo chmod -x /etc/cron.daily/mlocate

Problem solved, and no more seemingly random slowdowns by heavy activity on the HDD, which is slow as it is!

Also, turning off automatic checking of updates helps a lot too. It’s a great relief not to be interrupted in your… “work”, let’s call it, by heavy HDD activity, so it’s better to perform updates and package listing updates manually when it suits me.
