Why Users Love XRebel

We’ve had some real OutOfMemory problems in our production environment for quite some time. Once I got XRebel up and running I noticed that our most used webapplication uses around 15MB/User session. By tuning a few JSF parameters I got the average user session from 15MB to 0,5MB.

We found some very interesting side-effects right away. The worst of those was some badly coded Hibernate which would generate over 700 database queries. The JSF memory footprint was a bad surprise - some beans are in the session, that shouldn’t have been there.

We found it very useful to dig into the SQL queries. We quickly found some very lengthy and complicated queries. We also found that our session can get as large as 30 Mb - we had too many references to Spring beans in the session.
