Here are some numbers on pipe() vs socketpair() performance. The sample program used either pipe() or socketpair() to create a set of file descriptors. The main thread sent 512MB of data through the fds and then closed the sending side. A receiving thread read all the data until EOF and then exited.


Mac OS X 10.6.8

Pipes
real    0m8.501s
user    0m5.751s
sys     0m4.185s

real    0m8.462s
user    0m5.721s

Unix Sockets

user    0m6.329s
sys     0m7.301s

real    0m9.992s

sys     0m7.417s

Linux

Linux 2.6.18 VM

This benchmark only sent 51 MB of data because it was running in a VM.
