Yes clearly you can get rid of servlet stuff and go to frameworks like Play
or Spray!
Spray is more low-level and is better if you want pure REST (more is
possible too but it's more "manual" than Play). It's also 100% actor based
with akka.io
Play is full-stack and can help if you want more than just REST (it
provides everything to build web apps)... It uses Netty for now as network
layer (spray will be integrated later) and doesn't rely on actors for
network part (you can use actors in your application)

Both are performant.
In terms of connection pooling, you won't manage it anymore as with
servlets as you'll enter the world of stateless/non-blocking/async where
you have a very few threads switching very quickly instead of a big pool
like servlets.
So you have to stop thinking about sticky sessions, stateful sessions and
blocking code etc...
But it brings real benefits, you'll see ;)
