After our presentation at the JUG Saxony Day in 2019, we have been asked to turn the talk into an article for the iJUG-Magazin Java aktuell. The February 2020 issue just got published and features this article. So get yourself the latest Java Aktuell or, if you just want to check out the article, use this link to the PDF and enjoy. The article is in German.
High Performance Java – Hinter den Kulissen von Java
Die Zeiten, in denen Java der langsame Bytecode-Interpreter war, sind lange vorbei. Die JVM nutzt viele Tricks, um Code effizient auszuführen, und transformiert und optimiert Java-Code auf die ausführende Hardware. Mit etwas Wissen über diese Prozesse kann man vermeiden, dass man gegen die JVM arbeitet, und gleichzeitig mehr Geschwindigkeit erreichen. Selbst wenn man nicht die letzte Mikrosekunde jagt, ist es interessant zu sehen, welche Techniken die JVM einsetzt, um die Ausführungsumgebung besser zu verstehen.
We have often been asked why XLT (Xceptance LoadTest) is free but not open source. Now, after considering our customers’ business needs and the advantages of using open source as opposed to free software, Xceptance has decided to open source XLT under the Apache License 2.0.
Within the next 30 days, we will restructure the XLT code base and move subprojects into independent open repositories. We will continue to expand and improve the documentation. All code will be published on GitHub.
Xceptance will continue to maintain and extend XLT as before. Releases will be built and published by Xceptance on a regular schedule. Libraries will be published to Maven Central as part of the open-sourcing process. The latest releases will be available from the XLT GitHub repository as well. Of course, the GitHub defect tracker will start to be your source for feature development and defect fixes.
If you are interested in training, projects, or support for XLT and load testing in general, we of course also offer those services, and will expand this offering further in upcoming months.
By open sourcing, we are opening a new chapter for XLT and we invite everyone to join us. More to come!
