9. Front End Edge Server On the server side Frontends scale the fastest 3,333 Users / Front End Back End Stress Agent

10. Front End Edge Server The backend will scale with Pool count. 40,000 Users / Lync Pool Stress Agent Back End

11. Front End The edge server will scale with Pool count. 40,000 Users / Lync Pool Stress Agent Back End Edge Server

12. Front End The stress agents will scale the fastest 4,500 Users / Agent Back End Edge Server Stress Agent

14. Create users and groups Enable users for Lync Generate contact lists Create test location info.

15. Changing “Average Contacts per User” will increase subscriptions per user and increase processor utilization on the Lync Frontends.

16. Specify Stress Agents Service discovery Enable Modalities to test Set load variables such as number and frequency of PSTN calls

17. Be mindful of the features you enabled and how you configure them. For instance the Reach client can increase processor utilization on the Frontends.

21. Once desired configuration determined Generate files Directory created for each stress agent Each directory should be copied the corresponding agent

22. Runs all the tool generated tests Runs a specific test such as instant messaging

23. 2 categories, service & resource instrumentation Add to performance collections Analyze to determine services are in a healthy state
