For good real time performance it should not be disturbed to long time by something else. According to EDF and rate-monotonic scheduling interrupted by higher priority is OK provided execution times are short enough. Assuming dead line is equal to period latency up to just below period OK. What I have seen then using Ethernet is latency and jitter is very low but a few minutes in between there might be a quite long delay, milliseconds or maybe even more. Not sure where problem is it could of course be in my hardware or even in the measurement mechanism since I did not investigate thoroughly, will probably check more carefully sooner or later. Pretty sure Laptop is more than good enough, difference is not big. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
