The TPC-App subcommittee worked on TPC-App Version 1.1.1 definition clarifications, implementation clarifications, as well as review of Java and C# based reference implementations. The changes are effective immediately and are incorporated in the latest version of the specification, TPC-App Version 1.1.2 and are available on the web site.
TPC-App is a web service benchmark consisting of transactions involving database interactions, durable message queue operations, and displaying ACID properties running against a commercial application server. The primary metrics are Total SIPS (Service Interactions Per Second), SIPS per Application Server, Price Performance (for example $USD/SIPS), and the System Availability Date.
The majority of the changes were related to the recent adoption of the common TPC usage of the terms processors/cores/threads. In order to encourage TPC-App results, the subcommittee is working towards providing reference implementation source code. Currently, work has begun on a complete open source java implementation. Additionally, a C# based RBE driver application and post-processing tool for performing and analyzing TPC-App measurements is targeted to be released as open source and made available on the TPC web site.
