When EC2 first started the mental model was of a magic Pez dispenser supplying an infinite stream of instances in any desired flavor. If you needed an instance, because of a either a failure or traffic spike, it would be there. As amazing as EC2 is, t…

This blog is continuation to my last blog ‘Citrix Protocol on LoadRunner – Tips and Tricks Part 1’. In this article, I will discuss more tips that can be helpful when working with the Citrix_ICA protocol and LoadRunner. Number of vusers per LoadGenerator Machine: A LoadGenerator machine can run only a limited number of Citrix […]
In this article I will explain how to set up Forecast so you can use third party libraries. This is an extremely powerful feature that allows you to leverage code written by others to solve common problems. In this example I will use Boost library as an example and Boost.Regex to be more precise. The first […]
It wouldn’t be December without an avalanche of predictions for 2012. Here’s my contribution.
In this article, I am going to highlight some tips that can be helpful to performance test engineers to effectively work on Citrix applications. By understanding and implementing these points, script debug and test execution will be a lot easier. Points to consider while recording Citrix Vuser scripts simulate the Citrix ICA protocol communication between […]
Last week, Mac Slocum invited me to chat with him about mobile web performance. He had some great questions about apps versus mobile sites, common optimization mistakes, and whether or not different device owners have different expectations when it comes to performance.
The Java Remote Method Invocation (RMI) is a Java application programming interface that supports an object-oriented way of remote procedure calls (RPC). In this article I show you two ways to create performance tests scripts with Loadrunner for RMI-driven applications. As RMI is a Java-specific protocol, the Java vuser or the Java Record replay protocols mush […]
In my last article, I wrote about the paradigm shift in web application architecture and why performance testers have to re-think their strategy around testing Rich Internet Applications (RIA) for performance. Web application development processes and …
