    Performance Testing Openfire

    Jason

      Just wanted to share how Openfire scales and performs under a certain hardware specification. Our company uses an internal Openfire installation for our corporate communications. Hopefully this will serve as a sort of rough guide for those who are planning to set up Openfire in their workplace.

       

      For load generation, we have written some scripts in Java to  mock several thousands of virtual xmmp clients.

       

      Test Machine:

      Model name: Intel(R) Xeon(R) CPU E5-2640 v3 @ 2.60GHz

      Socket(s): 2

      Core(s) per socket: 8

      Thread(s) per core: 2

      MemTotal: 65687932 kB

      OS: Centos 7

       

      Setup

      Openfire 3.7.1.

      - increased JVM to 4GB (OPENFIRE_OPTS="-Xmx4096m" in /etc/sysconfig/openfire)

      - uses embedded HSQLDB

      - no other cache settings are changed

      - Unix file descriptors for the openfire process is set to 500,000.

      - Used a 64-bit JVM (1.8)

       

      Test data

      - 15000 accounts

      - no roster/groups

       

      Test

      - login only

       

      JVM usage when all clients are connected
