hi, we are relative new to jboss - just testing the migration from IBM WebSphere Application Server 5.1.0.4 to JBoss 4.0.2. Today we tested the performance between the two application servers...with no good result for JBoss, i think! :(
Our systems: -Linux/s390 (kernel 2.4) running under a zVM5.1 in an IBM z900 zSeries beast (production running z990). -IBM HTTP Server 1.3.28.1 -IBM DB2 8.1 -IBM CICS Transaction Gateway 5.1 (using IBM Java131 SDK) Our Application: It's a webfrontend, replacing the simple 3270 emulation (HOST) and using a DB2-Enterprise located at our mainframe. Connection to CICS is done via the CICS-gateway (haha). Server 1 runs JBoss 4.0.2 (with IBM SDK 142), server 2 runs IBM WAS5.1.0.4. Testtool is the LoadRunner/WinRunner Suite by Mercury. In first run, the Servers were virtually equipped with "Hardware" configured as: -server1(jboss): 1024MB, 1 VCPU -server2(WAS5.1) : 768MB, 1VCPU. WAS5.1 JVM Heap was min256 and max512 - same for JBoss => the winner was...IBM WebSphere Second run i reserved more memory for server1 within the zVM. Pushing it up to 1280MB. The winner was...IBM WebSphere. In the third run i changed the JVM max. heapsize of JBoss to 768M...the winner was WAS5.1 again but JBoss performance increased a bit. It can't be a result of HTTPD<->JBoss - when testing with JBoss' native 8080 the performance decreases...another bit slower. It can't be the VCPU - zVM is running with 3 dedicated Linux-IFLs. Their load when benchmark is running is round about 20% each...no problem here! Question is: where to look for? Or: Does IBM WebSphere always perform better than JBoss?
