Yes it’s for open source, but it’s a few hours away yet before I can use it
for anything real.

I believe it has to do with how the language is constructed. Lua is built to
be very lightweight.


Last time I checked, spidermonkey had some problems with delays on some very
specific cases due to its inner workings, but I can't tell for sure.


Will you share your ccxml/vxml integration? I believe that these 2
components are something that lots of ppl could use.

I know from a previous postings/discussions that the Javascript we use is
considered to be bad – performance and memory wise. Can someone explain a
little – who did the Javascript integration?


The reason I ask is because I am working on ccxml and vxml – and I need to
add ECMAScript due to compatibility with external tools/libraries


The impression I get from wiki is that Lua perform 2 x the speed of
JavaScript – does anyone know exactly why?
