Does the posix mqueue's not fit your need ? Have you tried them ? Do have some kind of numbers about your definition of fast ? For me, the POSIX mqueues seemed to work, though with some initial trouble which was fixed with a patch to the kernel follow this thread ( http://lkml.org/lkml/2010/4/2/293 ) , this patch is now queued for mainline inclusion for 2.6.35. There is also a new test suite to measure message queue perf in the rt-tests.
