The quick web search I did indicated that with some work, some users have been able to get latency down "under one millisecond", which is nowhere near what we need for even servo control. With RTAI, latencies of 10 us or better seem the norm when good hardware is selected and the right BIOS functions are turned on/off. Some of these articles are old, however, and better results may now be available. It would be good to actually run some of the RT-preempt tests on representative hardware before doing anything further.
