fastest (low latency) method for Inter Process Communication between Java and C/C++
...g overhead (or core caches?) is also the culprit
At the same time Thread.sleep(0) (which as strace shows causes a single sched_yield() Linux kernel call to be executed) takes 0.3 microsecond - so named pipes scheduled to single core still have much overhead
