A RTOS is an OS designed to meet time constraints and optimized prediction of process behaviour. It is not necessarily designed to be as fast as possible. > Would one gain anything speedwise using RTOS ? That can't usually be predicted. An RTOS doesn't need to be faster than a normal one, it just has to meet it's timing constraints. BTW: I had to use RT-Linux in a course on RT programming (scheduling, semaphores, Dining philosophers problem and so on) and learned that RTLinux is just a bunch of wild hacks to get some kind of RT into the Kernel. It was running on a normal Linuxkernel[1] and therefor, it wasn't a real hard RTOS. As what I know from electrical engineering, all hard RTOS are specifically designed for a task or device. Bringing hard RTOS to a Unix is IMHO almost unsolvable. So my advice is NetBSD, don't forget, it holds the Internet2 Land Speed Record[2] :-) [1] at least in our Lab [2] http://www.netbsd.org/Changes/#internet2-landspeed2 -- PGP FPR: CF74 D5F2 4871 3E5C FFFE 0130 11F4 C41E B3FB AE33 -- Der Geist des Kriegers sollte mit Beginn des Neujahrstages bis zum Ende des Jahres vom Gedanken an seinen Tod beherrscht werden.
