Monitor mobility for performance in Skype for Business Server 2015
Topic Last Modified: 2016-03-28
Summary: Learn about the Mobility Service (Mcx) and the Unified Communications Web API (UCWA) in Skype for Business Server 2015.
The Skype for Business Server Mobility Service (Mcx) and the Unified Communications Web API (UCWA) increase 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 running Lync 2010 Mobile, as well as Android and Apple devices running Lync 2013 Mobile, 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 must monitor mobility performance to determine when you need to increase your capacity.
Several limits influence mobility performance:
Request queue limit
IIS queue length
Other limits on servers that can influence mobility performance are a maximum of 12 concurrent sign-ins, authentications, session renewals, and terminations. These maximums do not need to be modified for most deployments.
