Thanks Per. Yes, I'll indeed use the socket connection which will be
the minimum process delays and overheads I can get.

In option 2 you responsed:

The delays and overheads in message queue (in my option 2) may be
smaller than the socket, but I guess that might require the external C
server to be compiled with the PHP module as they are totally
seperated.

Thank you.
