On the assumption that you're hosting with a linux infrastructure, this 
is simply done by just adding more memory! By default any spare memory 
will be used to cache common files.

If you want more control over it, then set your cache area up on a tmpfs 
backed partition. However, you'll then have to manage what you cache 
yourself.

With setups like this, it's normally the bandwidth of the network that 
becones the bottleneck. Maybe a bit of round-robin DNS would help with this?
