User development, A new message was posted in the thread "jboss performance tuning": http://community.jboss.org/message/525563#525563 Author : Peter Johnson Profile : http://community.jboss.org/people/peterj Message: -------------------------------------------------------------- The server.xml file covers only HTTP connections, not database connections.   In your *-ds.xml file, what is the maximum number of connections allowed? In your database configuration, what is the maximum number of connections allowed?   What database are you using?   What is meant by 1000 concurrent users? All logged in at the same time? Or all with active threads processing requests? I ask because in order to do the latter you would probably be looking at around hundreds of thousands of logged in users. For a shop with thousands or even tens of thousands of users, 50-100 concurrently processing requests is more typical.   Last Friday I was an a mini conference where a presenter was talking about load testing. His marketing department said thay they needed to load test for 30 million users. By the time he pinned them down on what they meant by that number, and told then what load tesing such an amount would cost, they finally settled on a much smaller number of concurrent users. In the end, his load test tested only up to 50 concurrently processing requests. And yes his system is now live and supports 30 million users, the vast majority of which are registered with the site but access the site maybe once a month. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525563#525563
