Hello all:
I had a feeling that clustering is more for HA rather than performance.
I am more interested in scalability and performance, and can any one comment on the following items:
By doubling the hardware for clustering, how much more scalable I can get and what about the performace:
1) CMP Entity Bean
2) Stateless Session Bean
3) Stateful Bean
4) Message Bean
Especially from my knowledge, there is no clustering for Message Bean,
If there are too many messages that a single hardware can not handle,
how can I effectively "clustering" it?
Thanks
Lei
