Hello, We've just finished some performance test on the jpa sample application from seam 2.0.0.GA, and Seam consumes a lot of CPU.
Has anyone had a chance to optimize Seam ? Is the dev team working on this subject ? (I'm really sorry - you're doing a really good work as you know, but those bench results are really scary ! ;( Some results Seam consumes from 2.2 (for 15 tx/s) to 4.3 (for 60tx/s) times more CPU than same application without Seam. Seam powered application saturated at 86 tx/s (cpu saturation). JSF application at 205tx/s (cpu saturation). Applications tested I've made various changes to the jpa sample application and tested each change : 1 - jpa sample. 2 - jpa sample without richfaces & a4j. 3 - spring sample (like jpa sample but with spring). 4 - spring sample with jsp instead of facelets. 5 - spring sample with jsp instead of facelets and JSF IBM 1.1 impl. - Test Platform - All test where executed with Websphere 6.1.0.13 and IBM JVM 5.0 SR 6 64 bits. OS : AIX Server : 6 CPU (2.1 GHz each) Power PC 5. Don't remember RAM size. I'll be able to give some more results on Monday - week end time now !
