Java on AIX Tuning Tool for Power & a Whitepaper for Java on Power7

I just noted two great new things to help those running Java on AIX and it seems hard to avoid Java these days! I was just monitoring a customer machine with 1500 WebSphere Application Servers (WAS) each with 100 to 150 threads so roughly 200,000 threads!!! More impressing was that just 20 Power7 physical CPUs was supporting this workload.
So here are two things that can help:
1. Java Performance Advisor (JPA)
2. Java Performance on POWER7 - Best Practice Whitepaper
I had better confess - I just spotted both of these and have not tried them yet but given the authors I am very confident.
If you get a chance to try or read them - let us know what you think via the comments.
I will have this on the to do list within the next 7 working days.
