1) don't use buddy replication for the server nodes. Since there are only 2, you don't need BR. 2) don't even bother with REPL. Use INVAL since they are backed by the DB. This will reduce chattiness and traffic between the server nodes. 3) You don't need singletonStore for the server nodes. You should allow both nodes to write to the DB if you are using INVAL. Only use singletonStore if you are using REPL. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250599#...
