When running a striped down version of our application (no complex business logic, only simple Rq/Rs [1k each]) we see TPS rates around 400+ with about 60% CPU utilization. Response times are below 100ms.
Sorry Holger but we didn't push our app to the CPU limit, but I'm sure we could get up to 500-600 TPS. We're using one Sun T2000 box (UltraSPARC 8-core CPU 1.20 GHz, Solaris 10, supports 32 concurrent threads of execution) with WAS 6.1. I can't comment on overhead when executing or calling code across multiple SCA Domains, multiple bindings or multiple languages. Our example only uses the WS binding, using Tuscany 1.0. If anyone on the list would like more detailed info, please let me know.

And message sizes of about a kilobyte. Charles can you elaborate more? ________________________________ From: Holger Winkelmann [mailto:[EMAIL PROTECTED] Sent: Fri 2007-10-26 04:14 To: [email protected] Subject: Overhead of SCA Container Hello, For a new Software Project we considering SCA and Apache Tuscany as programming model. The application has some Performance Numbers already. we expecting about 1000 SOAP requests / per second and need to make Desicins about what to do with the reqests. Teh decissions need to be dynamicly changed by different implementations i.e. JavaCode, Scripts etc. many of those scripts can be active at a time. We are looking to the interesting SCA programming model where these Components can be implemented in different languages. Now we are wondering the "SCA Container" will add some Performance overhead or not ? So far I understand for tightly coupled Components there cant be much overhead for Communication between the Components ?
