Hi, We are using JBoss 4.3 on Sun Solaris system and right now doing load testing on our application. Our application a small webservice, which is using JDBC and get the data from DB. Physical RAM on server is 2 GB. in server.xml under jboss-web.deployer we have the default value for maxThread is 250 and in jboss-service.xml we have MaximumPoolSize=20. We are looking 500 concurrent users during peak load. What should be the best value we should set in BasicThreadPool as well as in maxThread under server.xml ?
