What is the best approach towards scalability? Other than doing an experiment, you think this way. Most likely the bottleneck is disk i/o. Pretty much any approach is going to bog behind the bottleneck of a single moving disk arm. To fix that you can: 1. throw RAM at it. 2. use an SSD for the database . See http://mindprod.com/bgloss/ssd.html 3. see if you can find a JMS implementation that is more of a RAM hog. 4. tweak the OS and JVM to do what you can to optimise amount of Virtual RAM and disk caching RAM. If by some chance CPU is the bottleneck, you have have a look at how you could use two independent servers with message routed between them over a LAN. I would watch it running under as much load as you can muster to see what the bottleneck is. -- Roedy Green Canadian Mind Products http://mindprod.com I can't come to bed just yet. Somebody is wrong on the Internet.
