    I don't think that tells us very much. From 1.8 to 2 they added 
"significant improvements" that caused massive performance problems for our 
specific use case.  And I woulcn't bet too much money that the improvements you 
mention specifically address these issues ...
    

On the other hand, the 3.0 test that they report on indicates that the new JIT 
compile code is almost as fast as 1.8.  And the way around the performance 
issues with 2 was to use precompiled bytecode because the compiler was slow.  
This new JIT compile claims to not need bytecode, so I am optimistic....
