Speed up Internet Explorer 9 with the Add-on Performance Advisor
Truth be told, there isn't a whole lot to choose from, but if you do end up using a few add-ons or toolbars, you may run into the Add-on Performance Advisor. If any add-on takes too long to load, you'll see a notification at the bottom of your window (see above) -- and if you click through, you'll be shown a list of all your add-ons and how long they take to load (see right). It's just a matter of clicking Disable on any add-ons that are bogging down your surfing, and away you go!
From the same window you can also select the threshold for slow add-ons (but the default of 0.2 seconds is fine).
If you just want to see the general performance of your add-ons and toolbars, click Cog > Manage add-ons and every add-on's load time can be seen.
[Admittedly, a better question to ask at the start would've been 'does IE9 have any useful add-ons?' but that was beyond the scope of this post.]
