I'd guess you can - as far as I can see, the only thing that makes the 
DIR really use time is database access. With a database dedicated to it, 
one of the two should always be running, and (currently) the DIR 
database actions are never run in parallel. Even if the allover 
throughput is a little lower than possible for the DIR and the DB alone, 
the savings on network transit should more than make up for this.

Just don't forget to tweak MySQL to actually use all this memory :-)

By the way - if you want it as fast as possible you should consider 
using more than one SATA disk for the database. A dedicated array of 
striped hard disks should be better, especially if you give it lots of 
cache memory, too. And, of course, you could try to use a dual-CPU 
machine or even two machines with a really fast connection. Myrinet or 
Infiniband, for example :-)
