As example, re-deployment of the packages for my latest project is significantly slower (50 - 75%) and more CPU intensive than with 4.2.3.GA. Tried both with JEE deployment on default profile and minimal profile with micro-container services. Haven't got any feedback for general on-the-fly performance. | | I'm asking because although it's not valid comparison, I guess it would be easy to compare speed improvements with other open source application servers.

I'm now trying to establish some reasonable - easy to replicate test. Both test are having very simple deployment structure - so no Seam or things that would involve heavy pre-processing during deployment. | | The WAR file I'm using is on average deployed in about 9 seconds on 4.2.3.GA, whereas more than twice that time on 5.0.0.CR2/trunk; significantly more utilizing CPU as well. | | Test is performed using Java 5 and 6 on Mac OS X; and to have reference one test done on Java 5 / Solaris 10 (x86). Tomorrow I'll try to come back with more details. | "alesj" wrote : | I'm just about to commit MC changes - Kernel and Deployers. Deployers change will address scanning performance - if you have jboss-scanning.xml present it will scan accordingly to those rules. See Deployers project's test for jboss-scanning.xml usage. | "dimitris(a)jboss.org" wrote : | Can you move this to a forum thead? Ales, I think the whole point is that by default the server should be fast for the majority of deployments. If you need to deploy extra descriptors and stuf, the game is lost. | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4192696#...
