    SilkTest Performance issues

    I am running SilkTest 5.0 under 200 Mhz WindowsNT 4.0 with 64MB in one PC and 128 MB in another. With both of these, I have a number of issues when I record and playback scripts. Sometimes the agent stops responding. Sometimes the browser becomes too slow. (I am trying to findout a pattern for this so that I can report this to Segue)

    * Has any of you seen this annoying behavior of Silk?

    * Any tips on what processor/memory combination that works satisfactorily?

    Thanks in advance.

    Re: SilkTest Performance issues

    Yes I had both those things happen to me as well. Unfortunately I cannot pin down exactly what I did to make it better.

    I had been useing Silk Extensions (through Silk->Options->Extensions
    And I set Netscape 4.0 and IE 4.0 through this interface. Also I had IE desktop and I followed Segue's instructions to de-install it.

    Then I discovered that Netscape and IE cannot be run simultaneously through the same script session. So I disabled IE through:
    Start->Programs->Silk Test->Extension Enabler

    AFTER I disabled IE through
    Silk->Options->Extensions

    Honestly don't know why but things got way better. I will be watching the forum on this one, I really want to pin down what went wrong THIS TIME.

    Re: SilkTest Performance issues

    Performance problems may also be due to memory leaks with
    Silk and the browser, which I ran into over very long
    test runs. Below are a few articles from a thread on this
    earlier this summer.

    If you are encountering intermittent/strange failures during
    long (3+ hours) test runs using Silk 5.0 and one of the Netscape 4
    browsers (4.08 or 4.51) you are likely running out of
    memory. I have finally tracked this problem down, under NT 4.0. This
    problem does not appear to occur using Navigator 3.04 gold.

    The problem is obvious once ALL of physical memory is consumed,
    as you get virtual memory error dialog. But it is not at all apparent
    as you get close to exhausting memory (ah, those boundry conditions, eh?).

    The cause of the virtual memory error is Navigator -- it slowly
    consumes all of available memory, which appears to be a memory leak
    problem. But its not clear to me if Navigator is the real culprit or
    the Silk Agent's integration with Navigator. I have logged a problem
    with Segue support.

    Terry,

    Netscape's 4.x browsers are prone to memory leaks standing by themselves. On more than one occasion, I've left a Netscape browser open overnight or over the weekend, doing absolutely nothing but sitting on a home page and it's eaten up all available memory. It is possible that working these browsers in conjunction with Silk accelerates this process.
