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 (<a class="moz-txt-link-freetext" href="https://bugs.launchpad.net/gwibber/+bug/306497">https://bugs.launchpad.net/gwibber/+bug/306497</a>). 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 package. If someone knows how to remove gwibber without removing ubuntu-desktop, that would be awesome too!</li> <li>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! </li> <li>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.</li> </ol> I hope this helps! <pre class="moz-signature" cols="72">-- Best of luck, Bruce </pre> </body> </html>
