About 10 days ago I installed IE 7 at my home. I don't know if it is just my computer, but it takes longer to open the browser, to create new tabs and even to click on links if compared to IE 6.
The only things that I have installed is the Alexa Toolbar and the Google Toolbar.
Firefox is much, much faster.
Have you seen the same slow down when you installed IE 7?
UPDATE: Jamie (comment below) ask if I changed my start page. No I didn't, I always use "about:blank" as my homepage. I can't really confirm, but I'm start to think that Alexa Toolbar makes IE 7 super slow.
