Monitoring Mobility for Performance

 

Topic Last Modified: 2011-11-22

The Microsoft Lync Server 2010 Mobility Service increases the load on Front End Servers and Front End pools. Mobile devices that maintain a connection to the server even when the mobile application is minimized, such as Android and Nokia devices, impose a greater load than devices that terminate their connection to the server when the mobile application is minimized. As your mobility usage increases, you need to monitor mobility performance to determine when you need to increase your capacity.

Several limits influence mobility performance:

  • Available memory

  • Request queue limit

  • Concurrent connections

  • IIS queue length

Other limits on servers that can influence mobility performance are a maximum of twelve concurrent sign-ins, authentications, and session renewals and terminations. These maximums do not need to be modified for most deployments.
