    Right values for load testing parameters.

    What is the right or ideal values for %processor time, pages/sec(pages), Response time for any web application. When can i say that the application is working properly under load. Like for say 5,10,25,50 and 100 VU's and let the application be hotmail.

    Re: Right values for load testing parameters.

    You have asked this question in at least 2 other forums. Please don't!

    If this is a general load testing question, this is the proper forum.

    If the question is related to a particular too, then that tool's forum is the appropriate place.

    Re: Right values for load testing parameters.

    Satyajit,

    Assuming you intend this forum:

    The "right values or ideal values" are (should be) established by either system specifications (if they exist) and/or the goals for those parameters. If the specs don't exist, then one must test to determine what those values might be. What is right for your system will differ from another system. Generally speaking, you don't wish for high cpu usage (65% or greater for extended periods) or high paging rates.


    You can say the application is working properly under load if it meets specification or otherwise stated goals, service level agreements, etc.

    There are many other pieces of a system to consider. The level of your questions beg a full book response. I recommend you search for a book on this topic. Check the upper right of this page for "Links".

    Re: Right values for load testing parameters.

    What Jpensyl is correct, each system is going to have a different value based upon the level of complexity (or amount of logic, database calls, etc) of the application, the application server that application is using, the OS, etc.

    For instance the following links are thresholds for when a Windows 2000 system maybe overburden. (remember these are only general rules and each system is different)
