I assume you mean the driver the modifications I posted, unless Peter
hasn't checked in anything to CVS recently that I am unaware off ? (I'm not
online with my CVS snapshot at the moment...)

I would sure like to see your applications(or the differences between
them), so I can take a look at analyzing the discrepancies. Also platform
information like jdk version, vendor and OS information is interesting. I
suspect that the optimizations I did can have different effects depending
on the cost of allocating new objects in a specific environment.
