The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests. Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different). The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.
