Story of IHG GWT - Performance issues continue -FGC took long time

During the load test, we found out it took minutes for Full Garbage Collection.

After the search for the solution in the internet, we found out that -Xmn can be used to determine the space of young and old. So I adjusted the value of -Xmn several times, the FGC time is fine now.

Good reference of tuning up.http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html
