[jboss-user] [Performance Tuning] - Re: JBoss Performance Problems with SPECjAppServer2004

[PeterJ]

We have run specjappserver with injection rates in the high hundreds, using MySQL as the database, so it is possibly.

How many connections are you allowing in MySQL? Both the database and the *-ds.xml file must agree on the max number of connections, and I recommend setting both min and max connections to the same value. Also, I think that you need to set close you the IR*8 because each request will need a connection.

Also, have you seen:
