>> I reported back direct to Seb, because there was an initial problem, which was resolved. I have Sebs 3.4.55-1-rtai kernel, plus my own 3.5.7-rtai kernel running on 12.04.2 using RTAI-3.9.1 fixed by Shabby and memleak I also have my own 3.5.7-rtai kernel running on Debian 7.1 using the magma realtime from the current CVS (there are problems with Ubuntu include placements and _I think _missing inlines in maths headers, which cause magma not to build properly on 12.04) I also have the stock Debian rt-preempt kernel running on 7.1 and xenomai from John Morris's packages on Ubuntu 12.10 Overall I would rank them on latency 1. rtai 2. xenomai 3. rt-preempt The best performance by 20% was from my homebrew kernel, but largely because it is tailored to the machine it is running on and is far more radical in terms of removing all power management etc than you would probably want to be for any sort of distribution. Sebs kernel is ahead of xenomai on this machine, with rt-preempt notionally just behind that. In straight latency tests rt-preempt was not far off, but I am running it full time currently and have had some realtime errors when running a sim, which is a bit alarming given there is no base thread. regards ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
