Hello Remy, I like to have a low latecy predictable system. And I know the rt.wiki.kernel.org webpage. Also for example http://www.diyaudio.com/wiki/index.php?page=LINUX+Audio which is referencing zen-sources. But I would like to understand rt differences. That's what I have asked for. From viewpoint of application, I do not have a deep Linux or even kernel knowledge. Or do all the latest rt developments simply have no meaning or effect on the application?
