JDK 6 Performance Update, WAS v7, Fix Pack 7, and the G1 Collector

The Fix Pack 7 release for WebSphere Application Server v7 includes the JDK 6 SR6 update. It will update Java to Java SE 6 Update 16.

If you have not upgraded your WebSphere application environment to JDK 6, here are the reasons that you should upgrade to the latest. You will see many improvements with performance, stability and scaleability. In addition to these benefits, Fix Pack 7 with SR6 includes the new garbage collector known as the Garbage First or G1 Collector. It is concurrent and parallel with more predictability and better useability. It splits the heap into regions and young and old generational spaces are organized in sets of regions. This eliminates the need to fine tune "NewSize/MaxNewSize". G1 also provides incremental compaction in those regions by "evacuating" the regions that are full and fragmented...
