Yes, RTAI and Xenomai have significantly better latency behaviour than RT-PREEMPT.

Actually I dont think so, since this work changes internal plumbing, but next to nothing at the user level; plus version numbers arent a reward system - at least my ego will come out unchanged visavis the version number eventually chosen ;) There will be a more radically reworked version later this year which does away with NML and enables a split of RT (HAL/RTAPI/motion) and non-RT (UI, interpreter, task) onto different machines and hence possibly different architectures; that includes a 'non-PC' option for the non-RT part. That probably warrants a major number change. - Michael ------------------------------------------------------------------------------ Introducing AppDynamics Lite, a free troubleshooting tool for Java/.NET Get 100% visibility into your production application - at no cost.
