XMPP suitability for fast moving games

[timwhitlock]

This is really a general question about XMPP and not exactly about
Hemlock, but I'd appreciate your views.

Is XMPP fast and light enough for fast moving games? Think multi-
player shooters where character positions are updated [very close] to
realtime.

We've been looking at SmartFox for a back end and. (It doesn't
*appear* to be XMPP).
How does XMPP compare in your experience?

I'm aware that XMPP was designed for chat, and not for running around
3D landscapes with guns. According to Wikipedia it suffers from a fair
bit of redundancy.

Anyhow.. your views appreciated.

My personal view is XMPP is not the best choice for FPS game. You may need to looking into Binary socket protocols.

Also, multi-play FPS games need UDP connection. Flash's RTMFP protocol is a UDP protocol, but sadly I found string data has a low priority then voice data. And RTMFP seems to have built-in reliability checking for string data package, which can not be bypassed by ActionScript API and makes this protocol less efficient.

Regarding to game server, I would recommend Sun's Project Darkstar then SmartFox. SmartFox to me is more like a gateway

Thanks for the Darkstar tip. I'll take a look.
