Load testing of AJAX-based web applications will never be easier… that’s the message HP would have you believe should you encounter the marketing material provided by HP. In most situations the Loadrunner TruClient script type relieves the pain of scripting AJAX applications – making script authors forget the necessity of correlating AJAX parameters or separately having to code AJAX […]
In Zen And The Art Of Scaling – A Koan And Epigram Approach, Russell Sullivan offered an interesting conjecture: there are 20 classic bottlenecks. This sounds suspiciously like the idea that there only 20 basic story plots. And depending on how you ch…
Creating reusable load testing functions using SOASTA This article describes a framework for creating a reusable library of functions using the SOASTA toolset . It amazing that SOASTA doesn’t allow you to do this out of the box. So after a little hacking around, I discovered a way of achieving this. It made my life […]

These days, I’m seeing more and more sites that test well but perform poorly. Here are two tips to make sure this isn’t happening to you.
Load Testing and Citrix I wanted to write a high level overview of why performance testing with Citrix is different from other protocol adaptors and isn’t straightforward. This is possibly one of the least popular protocols for performance engineers to load test because its simplicity ironically makes it complex. Citrix is designed to deliver secure fat […]
Performance testing is complex, you can’t use just a screwdriver – you need a swiss army knife. I’ve seen yet another performance test tool that sells itself as needing ‘no scripting’ ability. A scriptless tool – ‘no coding required’. I’ve lost count of the number of tools I see selling with these points. If you’re thinking […]
The more I work on TruClient protocol, the more challenges I face (to implement more and more functionalities in scripts / config changes) and the more I explore on TruClient. This exploration sometimes take me very long to resolve issues and help me learn many new things on the way. Through this article I would […]
Loadrunner and a slow death. It was a good Test Managers’ Forum yesterday. Alan Wallet from ING did a presentation on the direction of test tools and how the landscape has changed.
