I definitely prefer BrowserUK’s approach of having just one thread that does the socket-handling, with two queues ... one (or more) for inbound work, and the other for completed. It gives you a very clean flow of control, and a method for accepting inbound work (and for disposing of completed work) that remains consistent no matter how big the loads get. The intake and outtake functions take a consistent amount of resources no matter how many workers there are, and a tunable number of workers ply their business no matter how backlogged the queues may get. (They can also easily shut-down a denial of service attack, because, so to speak, you have one faithful secretary whose job it is to answer the phone, and who also knows how big the intake queue is getting. This one process is in the position to know, with the power to act.) You can calculate the system’s optimal capacity to do work, set the knobs accordingly, and know that the system will churn through the work without fear of thrashing. Definitely the best scalable solution.
