Hi, @Leon: I am really grateful for your input. So basically, RMI is 10 times slower than corba. This is bad! I just found out, that I expose/access CORBA via Spring (and RMI) but that doesn't really help, since I simply cannot switch to Corba (lack of time) right now.
@Gareth: What do you think about the performance of ejb3? Did you integrate it with other frameworks such as Spring and/or Hibernate?
