I'm looking for good Java RPC mechanisms that are

• Secure
• Efficient (Fast)

What are the options other than RMI?

You should also consider how you will integrate this RPC stack in your code, for instance, if you are using spring framework, you should have a look at the supported remoting protocols. This will also give you some starting point to investigate on different RPC protocols.

One of the key point for performance of RPC is what kind of serialization is used underneath, have a look to this page for serialization API performance comparison.
