By executing tests in this normalised fashion it is easier to compare
results between different instances or different patch levels.
Roughly speaking there are two kinds of tests:
- VM tests: which summarise general performance of the instance,
without taking DD into account
- DD tests: which simulates many logins and interactions with DD,
while recording the session as a user would pereceive it from a
browser
By using these we should be able to consistently compare and improve
performance.
The original dd-stress-test.tpl.jmx tests file was prepared by
Teradisk with hardcoded instance, threadcount and duration values.
Testing should now be performed with `vm-test.sh` and `dd-test.sh`
respectively, and the template file should stay generic.
