We are going to need a little more detail here. In a normal environment 
1000+ "hits" isn't that much, even if the hit is generating a dozen 
queries per page.

A more appropriate action would be to consider the amount of transaction 
per second and the type of queries the machine will be doing. You will 
want to look into replication, hot standby as well as read only scaling 
with pgpool-II.
