Comet vs Akka

[James L.]

Are there any difference to both in term of efficiency and performance?
When should Comet or Akka be use in different use case?

Hello,

At first glance, Akka has nothing to deal with comet. Akka is a concurrency framework mainly based on the actor paradigm and comet is a way to push some data to web clients.

But I think it's true to say that Comet implementation in Play is based on Akka actors.

Akka is a good tool to implement Comet.

I've successfully used Akka to implement SockJS in my framework:
