 Description  « Hide

Using profiles Scott collected (with JIT turned off) for 2.1.1 and 3.1.1, I found that ORB initialization seems to show a significant regression:

Numbers are CPU seconds:

In 3.1.1:

10.527 GlassFishORBFHelper.getORB

In 2.1 is what I think is the equivalent

4.093 com.sun.enterprise.util.ORBManager.getORB

I do not have access to them right now, but IIRC other profiles with JIT turned on also showed a major regression in ORB start-up.
