[jboss-dev-forums] [JBoss Remoting Development] - JBoss RMI + Serialization performance issue

The page also gives the JUnit code that generated the graphs. we are trying out with 2.5.2. version. | | We are evaluating Java RMI and JBoss RMI over socket + Jboss serialization. We see that Java RMI with Java serialization is always atleast 20% faster than Jboss RMI + socket + Jboss serialization. | | i am unable to understand the below from the test cases. | | 1. The payload uses byte[1024] empty array always. and the object is never serialized. | 2. why byte[] as theres not thing there to serialize in it | 3. Even on using byte[1024] to be sent across using jboss and java rmi we see java rmi is superior on our machines. | | If this is the case then how ar the graphs generated? Or am i missing something very important. Please help. | | -- | ravi | Actually, the byte array gets wrapped in some Remoting objects, which do indeed get serialized. By "Java RMI with Java serialization" I assume you mean the "raw_socket" results, or maybe the "raw_rmi" results, and by "Jboss RMI + socket + Jboss serialization" I assume you mean "socket transport with jboss serialization". Is that right? If so, then I can't explain why you're seeing results different than ours. Who knows? Different machines, different jdk's, etc. By the way, before I released version 2.4.0.GA, I did a lot of testing and tuning, and, in the end, the performance of 2.4.0.GA and whatever the latest 2.2.x release was at the time were very close, within a few percentage points.
