Spining wheel appears in Safari & Eclipse Helios application on Macbook Pro

Hi All,

Spinning wheel appears very oftenly when I select any options from menus or via right click options in Eclipse Helios application. I have to wait for few seconds for the application to respond. Even I have same experience on safari while navigating or saving web content on to hard disk. What I need to do, to get best performance of Macbook Pro. Currently I'm using MacBook Pro for Java development activities using open source applications available on net. Some Plugins/Add on's when installed corrupts my existing eclipse/safari, makes unable to revert back to earlier state of application. Unable to quit Safari to shutdown system.

Please share your thoughts and be appreciate to help people in Mac World.

Thanks & Regards
