[ubuntu-za] Getting some performance back from Ubuntu 11.10

I just wanted to share a few tips & tricks that helped me see a
noticeable improvement with regards to Unity 3D.
1. *Remove Gwibber!*
Yes sad but true, gwibber was the main reason my desktop machine was
so slow. Response times when switching windows with or without the
alt+tab switcher was sloooow as well as launching and closing
applications. I had three gwibber-services running and in some
cases, one gwibber-service would be using around about 80-95% of the
CPU. I don't think I'm the only one suffering with this, open up
Ubuntu Software Centre and see the reviews for gwibber and this bug
filed over at launchpad.net
(https://bugs.launchpad.net/gwibber/+bug/306497). Now, I have a
pretty decent machine (Pentium 3GHz Dual-Core processor, 8GB's RAM
and a few 7200RPM SATA II HDD's), nothing fancy really but after I
removed gwibber I noticed a big difference in the desktop
experience, launching applications were snappier than ever before!
If you do remove gwibber, you will also remove the ubuntu-desktop
package. I really feel that gwibber should be completely separated
from the ubuntu-desktop package. If you do try and remove gwibber
and feel a noticeable difference with your desktop, please let me
know! I will probably submit a bug to ubuntu-desktop package
maintainers and ask them to separate gwibber from the ubuntu-desktop
If someone knows how to remove gwibber without removing
ubuntu-desktop, that would be awesome too!
2. *Ubuntu Panel Edge Reveal Timeout
*I hated the fact the menu always use to overlap the back button on
Firefox. To fix it I set the Edge Reveal Timeout in
CompizConfigSettings Manager to 350. It's a nice value, not to fast
and not to slow in revealing itself!
3. *Remove unnecessary services*
Ok, this is more to do with startup time, but I always use to see
brltty and bluetooth startup. I don't use those services, so I have
disabled them completely. To do this just run sudo update-rc.d
brltty disable && sudo update-rc.d bluetooth disable.
I hope this helps!
Best of luck,
