Result of running the test case Bm1.java provided by the customer on my test server. It's a very simple test case mono threaded (lower values are better):
JDK Version Time (ms)
32-bits 64-bits

6u19 18867 2630
6u20 18892 2651
6u21 18146 2645
We are seeing a big performance regression between 6u13 and 6u14.
The issue is seen with the -server VM argument set. Switching to -client improves the situation but still there is a little performance regression.
