Tomcat performance goes down after install apr. I followed this doc http://tomcat.apache.org/native-doc/, I think the different is I didn't set sslengine setting as I don't use it. And I saw the error in catilina.out, I simply ignore it as I don't use it.
I fired 300 concurrent calls from another server and I found tomcat just dead. Performance is much worse. Anything I did wrong?
