    Re: Things to check when buying Web Performance tool

    There is no "one main point". However, you may want to evaluate tools based on the following:

    1. The type of application being tested : E.g. client/server app, mainframe app, browser based app etc.

    2. Your budget : You need to keep in mind that the tools you purchase will involve software costs, cost of relatively good hardware to generate loads, cost of trained personnel who know the various scripting languages of the software, setup costs etc.

    3. Time : Depending on the amount of time you have for testing, you may want to look at web based testing solutions or inhouse solutions.


    Hope this helps

    the main point to check when selecting a load testing tool is to ensure that anyone who thinks that there is only one point to check when selecting load testing tools is not involved in the tools selection process.

    Re: Things to check when buying Web Performance tool

    We have just finished going through the exercise of researching a load / performance test tool for our product. Some of the issues that we considered were:

    1) Tool environment (i.e. Operating system)
    2) Tool performance (i.e. could the tool drive our product as hard as we need it to?)
    3) Budgetary constraints
    4) Reporting - how is the end-data presented?
    5) Portability - is the product licenced to a single machine, or can the product be installed on different machines at different times?
    6) Command line interface - we want to be able to shedule the execution of tests and suites of tests; we also want to be able to launch tests from a remote location (like from home over a telnet session).

    Certainly for us, the first two items were our primary concerns; and your requirements are likely different from ours.

    The best advice that I can offer is this:

    Clearly define what you expect from the products, in terms of must-have (mandatory) and nice-to-have(optional) requirments.

    Do this BEFORE you evaluate any tools - much like software development, tool evaluation can be simplified by having a clear definition of the goals and requirements beforehand!

    Have your requirments evaluated and inspected by your peers. Make them available to the developers, and attempt to solicit a response from them.

    Don't be afraid to add to your requirements once tool evaluation is underway - but be extremely wary of the urge to drop requirements (especially mandatory ones!).


    Hope this helps.

    Re: Things to check when buying Web Performance tool

    In my opinion before you purchase any tool, you need to brainstorm and get buy in and weight your requirements. What do you want to do? After you get the 'requirements' you should evaluate the tools on how well the fulfill your requirements.
    Also, I agree there is no one requirement that satisfies performance testing and it is different for everyone.

    Re: Things to check when buying Web Performance tool

    All the above mentioned points are good ones. Another big one is how far do you need the tool to scale - especially if you are testing distributed Applications that runn across Large Server Farms. If you are testing a sigle server then a few (or a dozen) load generating machines may do. But if you are testing a Large Server Farm as a target machine (20 - 30 Servers or more) then a big consideration is how transactions per second are you looking to generate? How much traffic load are you looking at and capable of handling? How many Load Generating Machines (10, 100, 1000, 2000, etc.) running how many Virtual Clients (100, 1000, 100,000) is the tool capable of scaling up to? T

    Re: Things to check when buying Web Performance tool

    1) type of application being tested : web , WAP
    2) OS
    3) Reporting and Result to store (Silk performer has own Database or comes with SQL Server)
    4) Simulation method
    5) Type of Load at tier : middle tier test possiable with SIlk performer like run against your EJB in middle tier
    6) Tool Company support : Segue is very very bad in that
    Thanks
