Hello, I've configured a two node JBoss 4.2.0GA cluster with farming deployment. I'm experiencing really low transfer performance of states and farm-deployed applications when using JGroups over UDP. Switching to TCP does the job immediately. The difference is immense 15minutes with UDP and a few seconds with TCP. Both machines are on the same network, no firewalls, routers whatsoever in between. Any ideas why this is happening? Reinhard View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053120#...
