[Freeswitch-users] 'outbound' IVR with JavaScript - garbage collection issues

[tuhl at ix.netcom.com]

My application dials 100's of numbers, waits for user to answer, 
plays a .wav file, and waits for some DTMF. I'm using the Javascript 
interface to do all this now (actually it's a Perl script which 
launches JS by sending jsrun commands through the RPC XML interface). 
But at high call rates, I'm running into JS garbage collection issues 
fairly quickly. At 10 calls per second, after about 300 calls it 
looks like JS GC kicks in and runs for like 45 seconds, during which 
time I can't launch any more calls with JS (RPC XML accepts them, but 
then they are getting Q'd up inside the spidermonkey code, and 
eventually some of them fail because GC is taking so long, etc).

Is JS the best way to do this application, and if so, any ideas how I 
workaround the GC? If not, what is the alternative (where I would 
still have access to the simple programming interface that JS gives 
me, as far as all the session. functions like waitForAnswer, 
streamFile, getDigits).
