<div>Im usually a lurker, but ill chime in here.. just to stir the pot a bit.</div>

<div>"speed" is being loosely thrown around here.... speed of the script interpreter is usually not an issue.</div>
<div>A voice dialog based application spends 90++% of the time in a waiting or "collect" stage, and the speed of the interpreter is basically moot.</div>
<div>Consumers will not be able to tell the difference is your script takes 50ms or 200ms to process what it collected.</div>
<div> </div>
<div>contention inside the interperter is usually the problem, not because its XML or javascript or whatever.</div>
<div>for example, thats the problem with your mod_spidermonkey.</div>
<div> </div>
<div>BladewareVXML will run 1000 channels at a time, and process the script in less than 100ms, and on modern hardware will take less than 20% CPU doing so.</div>
<div>compile it 64bit, and you can exceed 2000 channels and use around 30% CPU usage with a basic script.</div>
<div>we had to modify spidermonkey to have no global contention to acheive this.. it takes hardly anytime to populate the vars necessary for VoiceXML.<br></div>
<div>VoiceXML itself is not slow.. is it faster than raw JS? of course not.. but from a consumer perspective they dont know the difference.</div>
