[jboss-user] [Performance Tuning] - Re: Identifying performance bottlenecks

[otaylor]

I don't mean multiple JVMs ... I primarily mean multiple threads.   Almost all thread pool sizes in JBoss are configurable; to figure out which one to increase you need to figure out what is relevant for your app ... you could spend weeks increasing different variables without making a difference. For example, if in the stacktraces you see that you have 100 TP-Processor (Tomcat) threads all waiting for a response from your database, then you might want to update maxThreads. (That is unrealistic... few database configurations would increase throughput with more than 100 simulataneous connections but hopefully you get the idea.)
