We have some WebSphere 7 on AIX 6 that when instrumented with Introscope, lose significant performance. I've been working with CA support but am wondering if anyone else in the community has seen this type of issue. I'm using the WebSphere-typical.pbl. We have been basically pulling pbl's trying to find the area that may be causing the issue. Painful process. I am wondering if anyone has a shortcut?
