LoadStorm needs a little time to prepare the test resources such as the load generation servers. Our system is using each selected script(s) to pre-calculate the virtual users’ actions, how many servers will need to be instantiated from the cloud, random think times, etc. This produces essentially a test roadmap that our Scheduler and Summarizer modules use to coordinate all the HTTP traffic and correctly capture the metrics. Depending on the number of concurrent users and the duration of your test, the preparation of a load test can take 2 to 15 minutes.
