To elaborate.. there are factors beyond your CPU/memory. What kind of
diskdrive do you have? What is its transfer rates? What are it
hit/miss rates? How is the layout of the disk optimized for disk-seek?

A lot of commodity disk-drives are sub-par on these areas. This means
that programs will slow down because you are spending a lot of time
waiting for the disk-drive to give you bits because it keeps plugging
up its cache or not able to get various items off disk as fast as
advertised.
