There are some advantages and you can gain higher availability and therefore improved performance from clustering a single machine.
In my little apps I use terracotta. Open source Java clustering tool that lets me acheive a pretty good distributed cache without manually rewriting code to work with more than one JVM. They have thei great tool in the management console that helps performance tuning. check 'em out. The download comes with examples that are actually fun to play with. terracotta.org Dwayne Individual On 8/24/07, Andrew Hole <[EMAIL PROTECTED]> wrote: > > Hello! > > What's benefits of using Clustering/Session Replication on same machine? > > Thanks a lot >
