public class TestRTT
extends Object

In this test we use two atomic queues to send a message to a thread through one queue and get it back through the other queue. We only send the next message when the previous one comes back (i.e. not a throughput test). Thread pinning was used. java -Xms1g -Xmx4g -XX:NewSize=512m -XX:MaxNewSize=1024m -cp target/classes/:../MentaAffinity/target/mentaaffinity.jar:../MentaLog/target/mentalog.jar:../MentaAffinity/lib/jna-3.5.1.jar org.mentaqueue.test.rtt.TestRTT 100000000 The results: Old machine: Xeon @ 2.53Ghz quad-core.
