It's nice to see that the hotspot guys put a lot of effort into squeezing as much performance as they can out of the VM.
It's however a really shame when the library guys kill of any chance that the actual implementation (VM + libraries) will give any performance increase. (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6219959)
Does anyone except the hotspot people test and optimize their code?
Can we expect an optimized set of libraries as well as a VM for mustang?
