Gmail super slow on Safari 4
If you’re using Safari 4 and you also have the developer toolbar turned on, turn it off.
Similar to Firebug a few versions back, when you enable resource tracking it’s for all websites which is no good for Gmail or other sites that are noisy with the ajax requests.
The latest webkit version allows you to turn of resource tracking and any other developer tabs by website.
