more servers may help but don't forget that if you have a particularly 
popular key it will only be on one server, and that one server needs to 
be able to handle (max # of apache children * number of server box) 
connections.  so if you have 10 servers and each server runs apache with 
MaxClients = 200, you need to set your memcacheds to handle 2000 max
