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

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

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

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

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