FWIW PHP doesn't support reading args like ?id=5&id=3. PHP would only read in one value for id here. If I remember correctly, it would have to look like this for it to work with PHP: ?id[]=5&id[]=3

fastest (low latency) method for Inter Process Communication between Java and C/C++
...duling 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
Some shared memory measurement:
