Defrag your entire disk too as this really helps overall. In addition you can improve map download speed if you have a faster cpu or hdd. How? Well the maps are bz2 files which get decompressed on the fly after you dl them. As you dl them very fast you can be speeding up to 50% of the time decompressing if your cpu or hdd is slow. I do not believe multicore will help it is all about raw speed. So like I always try to stress the good old days of focusing on raw thread speed above all else is still a very important part of every day life for gamers.
