Load test: Percentage new users RRS feed

  • Question

  • On a load test, on a scenario, there's a property 'Percentage of new users'.

    The help below says 'Type the percentage of new users, also called first time visitors'.

    Yes, but what does this mean?

    A search in the help for 'Percentage of new users' drew a blank. There is a mention of 'Percent new users', on the 'About Scenarios' page, but all it says it they're edited in the load test editor. Nothing more.

  • The "Percentage of New Users” property affects the way in which the load test runtime engine simulates the caching that would be performed by a web browser.   The default value for the “Percentage of New Users” property is 100%.   This means that each web test iteration that is run in a load test is treated like a first time user to the web site who doesn't have any content from the web site in their browser cache from previous visits.   Thus all requests in the web test including all dependent requests such as images are downloaded (except in the case where the same cacheable resource is requested more than once in a web test).  If you are load testing a web site that has a significant number of return users who are likely to have images and other cacheable content cached locally, then using the default setting of 100% for “Percentage of New Users” will generate more download requests than would occur in real-world usage.   In this case, you should estimate the percentage of visits to your web site that are from first time users of the web site, and set “Percentage of New Users” accordingly.
