Class ShmTest

java.lang.Object

org.jgroups.tests.ShmTest

public class ShmTest
extends Object

Tests the speed of message sending/receiving via shared memory. Start the server first, then the client. The server and client use a simple (and stupid) alternating bit protocol to rendezvous; this could be enhanced into a ring buffer to increase performance.
