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 ! ;(
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).
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 18.104.22.168 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 !
