Significant Performance issue with JIRA 4.4.x on AIX 6.1

Question

We are trying to upgrade our customer running on AIX 6.1 JDK 6_64JRE 1.6.0 IBM AIX build pap6460sr8fp1-20100624_01 (SR8 FP1) and we are experiencing a huge performance issue. To give you an example during startup we get a 20 minutes delay before we can logon to JIRA:

Any ideas what to look for?

It seems we run into this problem. http://confluence.atlassian.com/display/JIRAKB/Poor+Dashboard+Performance+due+to+IBM+JDK+1.6

Our thread dumps indicate the same behavior around ResourceBundle processing.

We'll try an upgrade to the latest JVM Service Refresh and see how it goes.

I'm going to give it a try, thanks Nic.

First time I've tried that I didn't see anything of interest. So I'm going to run a thread dump to see if I can get anything from there.
