Which realtime system did you use? (at a guess, preempt-rt?) Are you planning to use the parallel port? If not, then 80k is usable. It _might_ be SMI. Is the latency generally good, with a regular crazy excursion? Try "latency-plot" from the command line to check this. If you see a periodic spike every 64 seconds, then SMI is likely, but that generally is a lot worse than 80k. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
