Can you give a brief explanation as to why and by what factor? Didn't
manage to find any simple explanation on the web.
First mentioned in Advanced Programming in the UNIX(R) Envionment by Stevens, pipe operations seems to be faster or
equell to any other IPC method (ignoring non synchronized shared memory, of course).
While it should be noted Stevens original recommendation pretains to stream (a.k.a bidirectional) pipes and AFAIK Linux
does not actually support stream pipes, as well as basing his claims on measurements on Unix systems other then Linux, I
never the less believe that the affarmation that pipes are as fast or faster then any other IPC method (bar non
synchronized shared memory) is true.
Which shouldn't surprise anyone, as pipes are actually the first ever Unix IPC
method, so it have a long time to evolve :-)
Cheers,
Gilad
