I don't understand why would you do that while there is simpler solutions? (i.e. nginx)
What you are trying to do seems a bit too hackish. FYI, APE as an internal "tick" implementation which automatically bufferize each message in order to send them every 50ms in a single JSON payload (this value is tunable in tick.h though). Therefore, and because of this, it would result in a framerate limitation and some unnecessary data copy (and thus performances degradation). Moreover APE (on the client-side) is doing a POST request eachtime there is data available (long polling) which is not really efficient in your case. BTW if you plan to support only HTML 5 client, you can use Websocket (which is enable on FF4 beta1 to beta7 and some not updated Chrome/Safari versions). Nevertheless, if you *really* want to continue in that direction : - Change this : https://github.com/APE-Project/APE_Server/blob/master/src/ticks.h#L27 <= 24FPS = ~40ms - Make sure you are posting on a channel to stream to multiple user (this will result in memory-copy reduction) - https://github.com/APE-Project/APE_Server/blob/master/src/main.h#L45 <= Decrease this value as small as possible to avoid data to stay in memory.
