I also had some recommendations from Alexey Verkhovsky that I try the latest trunk of JRuby (I was using 1.0), that I let the JVM 'warm up' with a few thousand messages so that the just-in-time compiler kicks in, and that I turn off ObjectSpace. It seems I have a ways to go before I get an accurate performance result. I probably won't get around to it for some time, but at least the info is here for anyone else that wants to try.Shane Harviehttp://www.blogger.com/profile/01016971334424471677noreply@blogger.comtag:blogger.com,1999:blog-2813261110497121234.post-20676594518971616392007-10-15T06:50:00.000-07:002007-10-15T06:50:00.000-07:00G'day Shane,<BR/><BR/>While you're at looking at "production" mode on MRI take a look at your JVM config too. Check things like Server mode, assertions disabled, heap size, etc are reasonable.<BR/><BR/>Also, try JRuby on compiled scripts(now that all nodes compile) see what the differences are - it's worth playing around.Joshua Grahamhttp://www.blogger.com/profile/13148399856460503228noreply@blogger.comtag:blogger.com,1999:blog-2813261110497121234.post-72535572698147668972007-10-15T05:10:00.000-07:002007-10-15T05:10:00.000-07:00Are you comparing like for like? e.g. are you persisting each message to disk before sending the next one in both situations? Or is one a pure in-VM protocol etc?<BR/><BR/>BTW if you are using jruby with JMS - you could embed the message broker inside jruby to avoid the context switch.<BR/><BR/>Also if you use the TCP protocol it'll be a fair bit faster than stompJames Strachanhttp://www.blogger.com/profile/12591119339035350067noreply@blogger.comtag:blogger.com,1999:blog-2813261110497121234.post-60593112626804311302007-10-14T08:05:00.000-07:002007-10-14T08:05:00.000-07:00The activemessaging setup can be found <A HREF="http://www.shaneharvie.com/2007/06/asynchronous-messaging-with-rails.html" REL="nofollow">here</A><BR/><BR/>I'm using ActiveMQ as the message broker, and Stomp as the protocol.

Did you use a Stomp protocol? <BR/><BR/><BR/>(I'm kind of new to the messaging parlance, so forgive my use and misuse of the jargon).Randitohttp://www.blogger.com/profile/17928693632349460428noreply@blogger.com
