The JVM and not getting in its way. :-) The JVM is the best way to deploy high performance software. HotSpot does a better job of optimizing code than any static compiler and GC-based memory management is faster in aggregate than malloc/free. Yes, folks can find micro-benchmarks that demonstrate that C programs are faster, but those examples don't scale as the complexity of the systems grow. Scala's immutable data structures make scaling apps much easier. > I know it uses scala, which has an > actor library, but according to the install instructions it default > configuration is with jetty.

Lift also use Actors for long polling so there are no threads consumed during the polling. > > > Now is the scalability built right out of the box.

There's no enterprise system that I know of that has this kind of requirement. Most enterprise systems need no support more than a few thousand open sessions. Even the largest companies don't have more than a few thousand people accessing the same app. Thanks, David > > > I am trying to create a web services framework for the enterprise > level, that can beat what is out there and is easy to scale, > configurable, and maintainable.
