Is there a way to introduce fake latency in Java RMI calls?

Question

In want to diagnose a bottleneck which happens when my client is talking to a server on the other side of the world. I'd like to run the server on my local machine and simulate the latency. Is there a way I can inject a brief thread-sleep in all remote calls? I'm not sure which remote call is the bottleneck, so I need to delay them all.

Second attempt to clarify: I don't want to copy-paste thread sleeps into every single remote method, because there are lots and lots of remote methods. I'm trying to find a way to inject a sleep into the RMI subsystem so all calls over RMI will be delayed.

Answer 1

WANem is designed to do just that. It works at the network level so isn't Java- or RMI-specific.

Answer 2

The Charles Proxy server has a feature where it can add throttling/latency to a connection:

I have been very pleased with Charles -- well worth the $50 for a license.
