The maximum size of your Internet Explorer browser cache is ### megabytes. Generally, cache sizes above 80 megabytes waste disk space and can actually cause slower performance.

How to adjust the IE cache size

Start Internet Explorer
Select Tools | Internet Options | General tab
Under Temporary Internet Files click the Settings button.
In the box for the amount of disk space to use, enter a value between 5 and 80 megabytes.
Click OK to accept the changes.

Editor Note:  Since I have a very fast Internet Connection I have found that setting my temp Internet Files to one Megabyte gives me the best performance.
