Results for the WebSphere Application Server performance tests
After performing our WebSphere Application Server environment performance tests, we charted our test results, interpreted the results, and created recommendations.
In most cases we defined our results as External Transaction Rates (ETR) and Internal Transaction Rates (ITR). ETR is the raw workload results. ITR is the ETR divided by the processor utilization rate, which shows the throughput as a per processor cost.
The tests we performed included:
- Separating the network streams
- Modify the database layout
- Modify logging setup
- Disable AIO for WebSphere Application Server
- Workload generation
- WebSphere Application Server version 6.0.2 versus version 6.1
- DB2 v8 versus DB2 v9
- SLES9 versus SLES10
- WebSphere Application Server 31-bit versus 64-bit
- OSA card versus HiperSockets
