Enhance Queue throughput ------------------------ Key: JBAS-1585 URL: http://jira.jboss.com/jira/browse/JBAS-1585 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Components: JMS service Reporter: Ivelin Ivanov > -----Original Message----- > From: Adrian Brock > Sent: Monday, March 14, 2005 2:35 PM > To: Ivelin Ivanov > Cc: Stan Silvert; Neal Byrd; The Core; Rebecca Goldstein > Subject: RE: JMS Reference > ... > I know you can get about x8 improvement in JBossMQ just by adding > some simple flow control. > > Instead of doing the "one in, one out" policy on the message cache > when memory is tight (i.e. move some old messages to disk to make > room for the new messages) > I did a simple test instead with > Thread.sleep(1000); > to slow down the senders and let the receivers clear some memory. > > The message throughput went from 1 million messages/hour to 8 million. > I did this test around JBoss-3.0.7 time when the performance was > very poor. > > I discarded the idea as too simplistic since the mechanism > requires blocking server threads. But it does show JBossMQ > could easily be improved if we had the motivation/resources > to work on the performance without degrading its reliability. >
