Today, a handful of performance testing products do support the Citrix protocol, but none with a customer base the size of LoadRunner. It never gained a major audience in the market, and ended its short existence in 2013. In 2007, Citrix purchased the “TLoad” testing tool from Edinburgh, Scotland-based ThinGenius. This includes Citrix themselves, who acquired a company specifically to fulfill the need in the market. LoadRunner has traditionally been the only serious choice for performance testing Citrix applications in the Enterprise. Once you leave the web testing world and venture into other protocols like Citrix, the gene pool gets pretty shallow and there isn’t a ton of information on it like there is for HTTP/HTML. Multiple times I have found myself doing Google searches during an engagement and used my own blogs to get myself out of a jam. I’ve also posted several blogs on the topic. For many years this document has been shared to educate on the basics of load testing Citrix. One of the first employees at Loadtester (Tim Chase) had so much experience testing Citrix applications, he wrote one of the first white papers on the topic. When native Citrix protocol support came out, it solved a big headache. Anyone else remember those days? I actually had to do a few of those exercises as a consultant. Before then, the only way to attempt a performance test was a combination of LoadRunner and WinRunner. There were a lot of legacy applications and we were migrating many of them to Citrix Metaframe at the time. I was working at a global systems integrator years before I would eventually launch my own consulting company, Loadtester Incorporated. I am such a geek I still have a picture to remind me of the event: I still have the original PowerPoint slide deck that Simon Berman gave in downtown Nashville about it. I was there in 2002 when Mercury first launched their Citrix protocol. My experience with Citrix goes back almost 20 years. What does this mean for performance engineers? What does it mean for the software testing industry? I think I know… How did we get here? Neotys has announced support for the Citrix protocol as BETA in the Neoload 7.1 release.
