jroper / With Grzegorz's improvements
Last active December 21, 2015 22:19
Scala incremental compiler improvements by Grzegorz Kossakowski. Actual runtimes are not so important here, since the two benchmarks were run on different machines, and also they make no attempt to ensure that the scala compiler is fully JITed, which during normal Play development offers significant improvements over these times as the compiler …
Initial clean compile of entire project:
[info] [info] Compiling 29 Scala sources and 1 Java source to /tmp/inc-compile/target/scala-2.10/classes...
[info] [success] Total time: 15 s, completed Aug 28, 2013 9:43:38 PM
Now simulate adding a method to a controller:

Transparent HEAD request handling in Play 2.1. Note that it may be more efficient to implement HEAD support in an action directly, as this may avoid unnecessary opening of resources or rendering things.

jroper / Ec2Client.scala
Created February 26, 2013 19:44
Barebones Ec2 client that uses the Play Framework WS API for provisioning instances. Handles authentication signing etc. If you want to use it, you probably want to read the docs: http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-RunInstances.html and update it to do what you need it to do.
