Safari Slowdown
I found that Safari has been slowing down and I would see the spinning cursor for several seconds every time I open a page. Thankfully This tip from Mac OS X Hints solved it.
If you go to ~/Library/Safari you’ll see a folder called Icons which caches all of the site favicons. After extensive use, the icon cache can get very large. Simply delete the contents of the Icons folder and the Safari slowdown will be gone.
To prevent it from happening again in the future, make the Icons folder read only. You’ll no longer see any Favicons in the bookmark window or menu, but it’s a small price to pay for the speedup.
