Internet Explorer includes an Add-on Performance Advisor which lets you monitor the load time and performance of its add-ons and lets you disable them if you find that they are taking more time to load.
IE Add-on Performance Advisor
To open it, right click on an area near the One Box and select Command Bar.
Under Settings, select Toolbars > Disable Add-ons.
This will open the Add-on Performance Advisor.
You can use it to warn you if it is taking more than a particular time to load. The default value is 0.2 seconds.
While add-ons, such as toolbars, can enhance your browsing experience, but they can also slow it down. Add-on Performance Advisor tells you if any add-on is slowing down your browser performance, and then allow you to disable or remove it.
This can help you make Internet Explorer start up even faster!
