If you expect to have more than a few hundred users and more than about 
10K bugs, I strongly suggest using a shadow database (via mysql 
replication).  You can run everything on a moderate machine with no 
problem.  If you want to geek it a bit, just add extra memory and dual 
CPU.  Definitely dont skimp on the disk drives. 

I have 500 users and 20K bugs and 16GB attachments on a Sun Ultra/60.  
It can get a bit slow sometimes, but not bad.  When I upgrade,  I'll use 
a shadow database on the same hardware.
