Load Testing Fallacies: The Test Scenarios Must Be Completely Accurate
Last time, I talked about why it is ok to start testing early in the development process. I’m going to continue that thought process to discuss load testing without complete performance requirements. This Load Testing 101 article says “If the real end user is going to do work with your application in a totally different way than you test you are as good as with no testing at all.” While there is a nugget of truth hidden in there, it is easy to take away the wrong understanding.
One interpretation of that statement would be that “you must have … Continue reading »
How User Ramping Works – Part One
How we add new virtual users to a test can be confusing when you’re first starting out with Load Tester, and sometimes can result in tests that do not ramp up to the number of users you expect or otherwise behave strangely.
User Capacity Analysis
How Many Users?
One of the most important goals of load testing is to find out how many users a particular website can handle simultaneously. For years, Load Tester has been the only product to give a direct, simple answer to that question. In the Load Tester 3.6 release the user capacity algorithm received a major overhaul, making the analysis more configurable, more flexible, and more accurate than ever before.
In this tutorial we’re going to look at some real-world load testing examples, and discover how user-capacity analysis tells us exactly how many users the web sites can handle.
Before We Begin
There are … Continue reading »

Business Impacts of Performance
One of the opening sessions of the Velocity 2009 conference was a joint session with engineers from Microsoft Live Search (Bing) and Google Search…yes, they were together on the same stage :>
Both organizations wanted to measure the effects of performance on the business – i.e. on revenue. Revenue for search sites is based on the number of searches and on the number of clicks on results. Both of the search giants have experimentation platforms which allow them to send a small portion of real users to a different version of the search platform, where they can modify the user experience … Continue reading »
New Load Tester feature – web page performance goals
Load Tester has supported the concept of a performance goal for quite a while, but the implementation has been rather limited. We have completed work on an improved version for our next release (3.6). Load Tester now provides the ability to set a performance goal for each web page and/or transaction in a testcase individually. Of course, you can still specify a global page performance goal, as you could in the past. In addition, users can specify a default page (or transaction) duration goal for an entire testcase and then override that value for each page or transaction. The performance … Continue reading »
