Lync Performance Counters


  • Anyone have a good set of performance counters along with thresholds as far as Conferencing goes?  Trying to determine at what point we need to add capacity before we start running into performance issues.

  • You can find a Stress Test Tool for Lync at Microsoft


    Lync STD Edtition Server supports up to 5000 users

    Lync ENT Edition Server supports up to 10000 users per server

    Virtualization lowers capacity with 50%

    All Lync Servers must have 16GB Memory and 4-8 core CPU

  • Hi Jeff,

    Besides of Deli’s suggestion, here is another tool called Lync Server 2010 Capacity Calculator for reference.

    And please also refer to this document Capacity Planning which will help you understand how to plan and deploy Microsoft Lync Server 2010 communications software so that you can adequately plan for the number of users in your organization and plan for the server load that their activities generate.

  • Should the Stress Test Tool (download link: run in the Lync front-end server ?


    I should have another Windows Server 2003 R2 x64 or Windows Server 2008 in the same domain as the Lync server (Current environment is 1 x Lync Front End server, 1 x DB server - Archive, monitor and database, 1 x Group Chat server. They are Lync Standard edition) and install the Stree Test Tool ?
