There are many ways to automate this if you wanted to.  One simple way to do it 
would be to rank the servers on how fast they respond.  Faster servers will 
thus be queried more, until such time as they are not fast, and then they'd be 
queried less.  Slower servers would be queried less to allow them to recover 
and become fast.  It's somewhat naive, but should match the real-world 
performance better than the round-robin does.
