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

Here is how to adjust your IE cache size:
1.Start Internet Explorer 
2.Select Tools >> Internet Options >> General tab 
3.Under Temporary Internet Files click the Settings button. 
4.In the box for the amount of disk space to use, enter a value between 5 and 80 megabytes. 
5.Click OK to accept the changes. 

 
Note: The faster the connection, the lower the number. I have DSL so I use 5MB and this works fine for me.
