Subject Re: EJB Performance Hit: Is there a workaround?

Steven,

Most APP servers that implement EJB try to shortcut
the RMI layer when both client and server are in the same process (for
example a servlet container + ejb container in the same process).

However, you must pass the RMI/RMI-IIOP/etc. layer for when two
processes 
communicate and YES it is a significant performance hit. You can find an
extended
discussions about this (+ all the derivative practices) in the
EJB-INTEREST list.
