Testing for Performance and Scalability 203
Profiling the Workload
The number of users increases over time. The number of users was 1, 10, 50, 150, and
300. There was no test mix and there was no think time.
Setting Up the Load Test
The load test simulates many clients accessing the application block at the same time.
Use the information in the workload to set the load test parameters. For more information,
see Creating a Load Test.
Recording Baseline and Application Block Metrics
The baseline tests are a subset of the Exception Handling Application Block performance
tests. The objective is to compare the overhead costs of using the Exception
Handling Application Block’s wrap handler with the equivalent .NET Framework
method and with Enterprise Library 1.1.
Table 18 is the template to record the performance metrics both for the baseline and
for the application block.
