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 sys 0m4.078s Unix Sockets real 0m9.782s user 0m6.329s sys 0m7.301s real 0m9.992s user 0m6.360s sys 0m7.417s
Linux
Linux 2.6.18 VM
This benchmark only sent 51 MB of data because it was running in a VM.
