    Hi All ,

    Can anyone please let us know , what amount of Load can a Lisa service sustain for Performance Testing and what impact will be on the server while PT testing going on.

    I have been asked this question by my senior that :

    Do you know how much load LISA can sustain.

    Hi Saurabh,


    You can have a look at this:


    The load LISA can sustain is only limited by the resources of the system on which the VSE is running. So these are some good practices:

    • Get a powerful system, make it dedicated to only running the Performance VSE process
    • Give the VSE enough RAM via JVM option -Xmx=, also assign the immediately the minimum RAM -Xms= equal to the maximum RAM to avoid JVM memory allocation during the load test.
    • Only use default out-of-the-box VSMs (so no customized steps) and run them in "Most Efficient" execution mode
    • Set VSE logging to OFF or ERROR level


    Many of the above and more are also mentioned in above documentation.

    Hi Saurabh,

    First you need a perf license for the same. Secondly, there are many other factors which will have an impact on load sustained by LISA. Danny already few key one in her post.
    -- Count of VS deployed on VSE
    -- Type of services deployed on VSE
    -- Log Level
    -- Memory allocation
    -- Machine hardware configuration etc.
