Re: [JBoss-user] JBoss Performance vs. Orion

[Julian G. <jul...@ya...>]

If your problem was throughput, and you were using Tomcat 3, you should have
tried the Jetty integration too. Many people have reported much improved
throughput from this configuration. JBoss.org runs on it.

If your problems lie more with the ejb container, someone else will have to
answer !

Good luck,
