I'm writing a rather major project under FreeBSD, and making fairly heavy use of message queues so that multiple processes can communicate. I am finding the response times for message delivery between two given processes to be pretty horrid, typically about 1 second per message set (send query from process A to process B, then process B sends a response back to process A and process A displays the response). Before I contemplate switching to named pipes or writing my own communications structure in shared memory, can someone tell me if there is anything that can be tuned in the kernel perhaps, or anything that will speed up message queue processing?
