Scala really makes Play2 shine. We really need a good example of using Play2 with ZMQ.

Why?!? Play2 is essentially a collection of specialized Akka actors. When you run Play, you get Akka integration for free. Having an architecture where your Play actions send Akka messages to a cluster of computational nodes/actors requires about 3 lines of code and 5 lines of config. Ridiculously scalable.

Scale what?

Not really. Scala has a lot of good points but it's very ill-suited to web development because of compilation times.

Play1 could compile templates in a few tenths of a second while it takes 7-10 seconds for each template in Play 2, which is unacceptable when you do this all day long.

I predict Play 2 will not be around in a year from now for this reason, there are just better and faster ways to do this.

The Play team or someone else could just re-implement the template layer as Groovy once again.

Scala has a lot of nice things going for it, but using it for the Play2 template language was stupid - the benefits do not outweigh the drawbacks at all.

When you make changes to a template it takes a few seconds to recompile the template (once ) then after that it load much faster since it doesn't need to compile a second time. In addition the resultant code is rendered much faster the then old Groovy templates ( in my experience ). Is this more of a development time issue for you or are you noticing issues in a deployed system ?

We've been very pleased with Play 2.0. Very easy to use and very productive :)
