Hi Deepal,
The problem we had in clustering is having the listen to specific events in
the Axis2 execution. For example context creation, context removal, mep
completion. So it is not possible to do it with a module based approach :-(.
But performance is certainly in our mind.

Hi all ;
When we implement features like clustering , context serialization we
need implement that such a way it will do a minimal change to the kernel
code and its API. As I know both of them can be implement as separate
modules (mar) and provide what ever necessary API from the kernel.Once
we implement them such a way then if user want he can engage that else
system will work w.o any dependency to either clustering or context
serialization.
I agree that we need to add new features , but in the meantime we have
to think about the performances as well.
Thanks
