The reason it might offer better performance does most likely not come from the kernel, but because in such a small system less services are running, which might eat less CPU time. Will performance be better? Depends on what you mean with performance. If you apply Xenomai/RTAI to a vanilla Linux kernel throughput and number crunching (performance) will get worse and determinism will get better. Real-time is not about "performance" (speed, throughput), but about determinism and those are conflicting requirements. You can have a look at an article of mine for a more detailed explanation of what I mean: http://www.eetimes.com/design/embedded/4204740/Getting-real--time--about-embedded-GNU-Linux Regards, Robert > > > > _______________________________________________ > Rtai mailing list > r...@rtai.org > https://mail.rtai.org/cgi-bin/mailman/listinfo/rtai ...A clever person solves a problem.A wise person avoids it.- Einstein My public pgp key is available at: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x90320BF1 _______________________________________________ Xenomai-core mailing list Xenomaifirstname.lastname@example.org https://mail.gna.org/listinfo/xenomai-core
