[infinispan-dev] introducing an artificial network delay

Hello, I'm running some performance tests; my goal is to alter the code for the Lucene Directory to use optimal batching and Flags, but to make sure I'm improving performance for DIST and REPL configurations the only option I'm having is to run it on a real cluster, which is not doable right now. So as I'm running tests on my laptop, network IO is not real and I suppose it's not representative of real life bottlenecks. Is there some option I could set in the jgroups configuration to introduce an arbitrary delay, or even some degree of random packet losses? Or should I extend the transport to introduce some sleep() in interesting points? Maybe adding a slow-down interceptor around remote invocations? suggestions? thanks in advance, Sanne
