For instance the archlinux -rt kernel uses high resolution timers (probably based on your hardware's TSC) and is much more accurate than the ticker based scheduling ever was. > I just asked you to help to get the Wiki up to date and to _discuss_ > controversial opinions, as well to explain some things that aren't > explained. > > I can't understand the resistance and hostilities.
