I have seen this question (answer: JGroups) and I'm thinking about implementing something with JavaGroups or straight RMI but speed is of the essence. I'm not sending large amounts of data around (content of MIDI Messages, so 3 bytes each, no more than say two messages every three milliseconds) and this will be all on the same machine. ...
Hi! I just read the Trail on RMI from sun at http://java.sun.com/docs/books/tutorial/rmi/implementing.html When I run the example, the JVM does not terminate although main has finished. Is RMI spawning a Thread somewhere internally? What is the behaviour of multiple Threads spawned in main, after main exits? Is it a clean way to let ...

I'm trying to optimize an app that makes a lot of RMI calls. According to JProfiler, more than 30% of the CPU time is spent in the sun.rmi.server.LoaderHandler.urlsToPath() method, which is apparently getting called during marshaling. This method calls URL.toExternalForm() Is that normal? I haven't yet figured out which objects are gett...
