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: > System V message queues are intended for just that; IPC = Inter Process > Communication. 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. Kind Regards. Jim
