             Summary: Major performance degradation from JBoss 7.1 to Wildfly 8.0.0-Final.
                 Key: WFLY-3404
                 URL: https://issues.jboss.org/browse/WFLY-3404
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 8.0.0.Final
            Reporter: Timothy Heider
            Assignee: Jason Greene


I have deployed my application to Wildfly 8.0.0 Final and it is almost unusable now.  We have rolled back to JBoss 7.1 (same application WARs) and it works fine.  

Specifically what seems to be slow is our SOAP web services are taking up to 8 to 10 seconds to respond.  We have user concurrency of probably 10-30 users at once hitting these services every 10 seconds or so.

On JBoss 7.1 these services all respond sub-second.  The database is totally unburdened and the server is 90% idle all the time.

We have one service endpoint that is a Comet queue wait call.  Probably 10 users are waiting on that.  Did something change between JBoss 7 and Wildfly 8 that might cause that to not work now? (e.g. too small a thread pool that blocks until the 10 second comet call breaks on a timeout?)

We will try 8.1.0CR2 but I wanted to report we're investigating this and see if you can help us.  Thanks!
