I am currently looking into Sun One App Server 8 as a corporate J2EE App Server for my company. I have done a proof of concept and so far everything seemed fine. However, I am concerned about the performance in the production environment and I am not able to simulate this now. I would like to have the feedback from the current and former users of this Application Server, particular any issues and problems you encounter.
