Use TCP. On most modern systems (eg Linux ;-) ), TCP especially on the local
machine is very efficient. Not quite as efficient as a Unix domain socket,
but close enough that no one will notice.
I have not experienced noteable performance differences on my AIX box either.
Of course when doing client server communication I always suggest PVM3.
It can be configured to do nearly all current communication methods,
including hardware based ones on MPP/NUMA systems.
