Alessio Soldano commented on CXF-6421:
--------------------------------------

I've created a PR with the changes I've been testing on 3.0.x-fixes branch: 
https://github.com/apache/cxf/pull/73 . The reason for the PR instead of direct 
commits to master and branches is to let someone else review the changes first, 
as the change set is quite big. I can of course prepare a proper patch for 
master too.

The changes in the PR are granting a ~ 2% performance improvement on my local 
JAX-WS client benchmark application.

> I've been experimenting a bit on slimming the Exchange map down; basically, 
> Exchange currently store a bunch of stuff that is not strictly required 
> either because there're already direct accessors the data (Bus, Service, 
> Endpoint, Binding, BindingOperationInfo) or because the data can be easily 
> retrieved using stuff that's already in the map (ServiceInfo, InterfaceInfo, 
> BindingInfo).
> This is relevant because the Exchange map is copied into the Message context 
> cache, so the slimmer it is the faster it's copied (and ofcourse we save 
> memory).
