I grew tired of staring at the beach ball every morning so I decided to do something about it. I long thought the culprit to be flash based content; through my research to disable Flash I discovered the ClickToFlash Safari plug-in which gives you the option to view the flash based content on demand rather than having it pre-loaded. Some websites have multiple flash-based elements which can be taxing on memory and CPU cycles, particularly with the multi-tabbed web browsing I do. I did not want to disable all plug-ins as I like some of the Safari 5 extensions, that coupled with the fact that flash-based video is widely used.
for ubuntu 8.04LTS through 10.04LTS you can resolve the problem which creates the error message:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:

LC_ALL = (unset),

are supported and installed on your system.
