[asterisk-dev] (Getting OT) Asterisk AGI 2.0

Would MAGI this be more robust than OrderlyCalls or Asterisk Java under 
high load (tested in real world)?

I know this is getting into user space, but under high load are any of 
these options better than using the standard AMI and and FastAGI? 

Libraries and Frameworks
Java

    * OrderlyCalls (successor to JAGIServer) offers full support for 
FastAGI and Manager in an easy-to-use Named Service environment. 
Includes Web Deployer for developing integrated VOIP-HTML applications.
    * Another Java framework for FastAGI: 
http://tanesha.net/Wiki/JastAgi.html
    * Asterisk-java now also supports FastAGI in addition to the Manager API
    * The Brazil Web Framework supports FastAGI and Manager directly 
though its HTML template system.

Thanks,
Steve
