[Freeswitch-users] mod_v8 pushed to git master!

[Peter Olsson]

Not right now. It should be quite fast though, since it doesn't run inside
a VM as Spidermonkey does (and the Spidermonkey version used in FS was also
quite old). Also, other projects like Node.js delivers good server side
performance, so I hope it will prove to be quite efficient.

I've built this project at home only, so I don't have any load testing
resources, or other performance testing tools available. Hopefully we'll
get more input in this pretty soon, as people start to try out the module.
