[jboss-user] [Performance Tuning] - Re: Slower JBOSS 4

Have you had any luck in your research? We ourselves took a big performance hit when we upgraded to 4.x, although we made several new deployments at the same time that could be part of our decreased performance too. Here are a couple of links you might have already seen - if not, they are helpful. A JBossian blog posting on rmi gcinterval and also stack size: http://blogs.jboss.com/blog/acoliver/2006/03/21/If_you_dont_do_this_JBoss... Sun's JBoss On Solaris Best Practices http://www.sun.com/servers/coolthreads/tnb/applications_jboss.jsp Here's an extensive article on slimming your jboss installation. It starts with tuning tips http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossASTuningSliming And you probably know this one too, but just in case: http://java.sun.com/docs/performance/ Along with this: http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html If you haven't yet already, check out http://java.sun.com/j2se/1.5.0/docs/tooldocs/share/jstat.html#gcutil_option I use that on production boxes instead of verbosegc And jmap with the -heap option is awesome. The -histo option is pretty cool too. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4032147#...
