Changing the Virtual Memory settings will increase your CAD speed.

Leigh Lundy sends a tip on managing workstation memory to increase performance.

"I was having issues with my 3D CAD drawings; it would take several seconds for my program to respond to commands like Move or Zoom. I found that my computer's virtual memory was set below the recommended size. The default was set to 2,625MB, and the recommended setting is 5,368MB. After I increased this value, my 3D drawings are responding like small 2D drawings."

Notes from Cadalyst Tip Patrol: Speed in CAD is always of the utmost importance. The workstation you are using will determine the speed at which the program can operate. Be careful, however, when increasing the amount of virtual memory your workstation uses. If you are unsure about what you're doing, get help from your IT department. Virtual memory is a method used by many computers to manage memory usage. It allows multiple programs to be opened at one time. (Back in the days of DOS, we could typically open only one program at a time.) Virtual memory manages which programs are currently stored in your RAM or on your hard drive. The higher the number setting in your virtual memory, the more programs it can work with. Memory can get bogged down in a workstation if it is left open for long periods of time. It is also a good idea to turn your machine off on a regular basis to reset the memory.

It's probably worth noting that as cheap as RAM is today, adding additional RAM will help out also. But 32-bit operating systems can only address so much RAM, so if moving to a 64-bit O/S is an option, look into it for even greater speed increases.
