Here’s how:
Open Internet Explorer 8, and click Tool> Manage Add-ons. This Window will open up:

Now, under Add-on types, make sure Toolbars and Extensions is selected and scroll down the list of currently installed add-ons. You can even see how long it takes some extensions to load, using the info bar at the top.

Simply pick a toolbar or extension that you suspect is detracting from your speed and click the Disable button at the bottom.

If you’ve got more than one you want to disable, you can also select multiple items by holding the Ctrl key while you click. Simply select all you want disabled and hit Disable all.
Now restart IE 8 and see if you’re speedier!
