Normal limit for a PC architecture. > If I can't schedule periodic threads with less than 10us period that will mean > that if the thread is used to aquire samples from a DAQ board I will have a > 100KHz sampling rate limit, which I find a bit low for my needs.Is it possible > to achieve higher sampling rates with RTLinux? Try the Comedi library <http://stm.lbl.gov/comedi/>: it has drivers for lots of DAQ cards, and is RTAI and RTLinux compatible. If your DAQ card supports autonomous on-board sampling (i.e., the card does the high-frequency sampling, and returns a buffer to your software), you can use that feature.
