Best practice: Adding a BlackBerry Enterprise Server component

You can use the BlackBerry® Performance Engineering Resource Kit to test the addition of a BlackBerry® Enterprise Server component. For example, before you add instant messaging to your organization's environment, you might want to know if the computer that you specify to be the instant messaging server can perform the job.

Before you add the BlackBerry Enterprise Server component, you should establish a baseline for the performance of your current environment. By comparing the performance of the BlackBerry Enterprise Server both with and without the component on the same computer, you can eliminate performance differences that are based on hardware. These comparisons can be considered more valid.

After you establish the baseline, you install the new BlackBerry Enterprise Server component on the same computer or another identical one. Both versions of the BlackBerry Enterprise Server might run on separate virtual machines but on the same hardware.

You must create new profiles for each relevant workload, and turn on the new feature in the BlackBerry Infrastructure and Smartphone Simulator.

You should also test the BlackBerry Enterprise Server component under all relevant workloads. That is, if the BlackBerry Enterprise Server component applies to a feature that you expect to give to only a dozen users, a heavy workload might be an inappropriate test. In the absence of other information about what the relevant workloads are, you should run tests using light, medium, and heavy workloads.
