Aside from Howard's answer, I personally suggest running a pool of slaves 
that are completely separate from the master.  For example, my replicas 
have 90 indices, while my master has about 10, the minimum necessary for it 
to function for its purpose (accepting writes from clients).  This keeps 
the master from having to do double-duty, and makes loading the master a 
much simpler task than the replicas.  Just food for thought. ;)
