This is a special and short issue of the PurePulse. Load testing is a critical part of testing all multi-user applications.
More applications fail in production from multi-user problems than from any other reason.
If you are responsible for a multi-user application then you should probably be doing load testing. The alternative to load testing is to roll out an application and find the multi-user problems when there are 100 or even 1000 live users in the field. This is not recommended. Load testing is something all multi-user applications should go through prior to deployment. All of these customers, and hundreds more, are fully reference-able.
