Performance and scalability: local vs remote in proc performance

  1. local vs remote in proc performance (1 messages)

    I've read a lot of references to the performance penalty of using EJBs with remote rather than local references and wanted to get a handle on it. However, my test results surprised me because (JBoss 3.0) it seems to show very little difference in the cost of local vs remote within the same jvm. Of course using remote reference in a standalone client and thus in another jvm was two orders of magnitude slower.

    Do conatiners optimize these method call in some way. Is it just JBoss or do they all do it?

    For example the create method in milliseconds on Pent II:
    local : 0.0841
    remote : 0.1051
    standalone : 10.706 (101 X greater than remote)
  2. Yeah, containers do some optimization....In case the call is in-process
