Testing for Performance and Scalability 211
Profiling the Workload
The number of users increases over time. The number of users was 1, 5, 10, and 50.
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 profile 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 Cryptography Application Block performance
tests. The first objective is to compare the cost of using the Cryptography Application
Block to encrypt and decrypt plaintext with the RijndaelManaged provider against
of the cost of using the .NET Framework to do the same thing. The second objective
is to compare the cost of using the Cryptography Application to hash plaintext with
the HMACSAH1 provider and then compare the hashed value with the plaintext
against of the cost of using the .NET Framework to do the same thing. For information
about acceptable performance limits, see Measuring Performance.
Table 22 is the template to record the performance metrics both for the baseline and
for the application block.
