Though I haven't used it, based on its architecture I would guess  
that ASM is significantly faster and less memory-hungry.  However,  
given that:
- Our code using serp works.
- It's easier to work with serp.
- Performance is not of primary concern at dev time.
- The cost of the little runtime bytecode processing we do is  
amortized over the life of the app.
I would put an "upgrade" to ASM way, way down on any OpenJPA TODO list.

If you're interested in bytecode processing, Patrick, Marc, and I  
were just discussing a bytecode-related project we'd really like to  
see someone work on once OpenJPA stabilizes...
