[Jboss-dev-forums] [Design of JBossXB] - Re: optimizing introspection/reflection

[<hei...@jb...>]

Well, after the last improvement (LinkedList->ArrayList), it became evident that creating the reflection wrapper (getter, setter, field access) is the biggest bottleneck. I did some quick prototype, similiar to what you did with ClassInfo and FieldInfo and it turned out that performance increased significantly.

IMO you are on the right way. Although i would suggest to cache this information per Marshaller/Unmarshaller instance and not statically/globally. This way we can additional synchronisation and it would still be possible for the callee to reuse particular instances per usecase.
