When is Distinct ONC RPC/XDR for Java a better choice than RMI and Why?
Distinct ONC RPC/XDR for Java is the clear winner when any of the following is important:
* Whenever you need to interoperate with C or C++
* When compatibility with legacy systems is required
* When ease of programming is an issue. RPC is smaller and much easier to program with compared with CORBA based programs.
* When your distributed application is requesting the execution of functions on a remote system and speed is an issue.

A typical procedure call in a distributed application consists of a function call issued by the client to a server. The server executes the function and returns the result to the client. In most cases the call itself and the returned results require the transmission of just a few packages, with the workload being the processing done on the server side.

We have taken some time to write test applications in both Distinct's Java RPC and RMI to illustrate the speed issue. In all our tests Distinct ONC RPC/XDR for Java resulted 40% to 50% faster than RMI. We are making available two of the test programs used in this analysis.
