Norman Maurer eb34cbb2d8 [#2685] Epoll transport should use GetPrimitiveArrayCritical / ReleasePrimitiveArrayCritical 
Motivation:

At the moment we use Get*ArrayElement all the time in the epoll transport which may be wasteful as the JVM may do a memory copy for this. For code-path that will get executed fast (without blocking) we should better make use of GetPrimitiveArrayCritical and ReleasePrimitiveArrayCritical as this signal the JVM that we not want to do any memory copy if not really needed. It is important to only do this on non-blocking code-path as this may even suspend the GC to disallow the JVM to move the arrays around.

See also http://docs.oracle.com/javase/7/docs/technotes/guides/jni/spec/functions.html#GetPrimitiveArrayCritical

Modification:

Make use of GetPrimitiveArrayCritical / ReleasePrimitiveArrayCritical as replacement for Get*ArrayElement / Release*ArrayElement where possible.

Result:

Better performance due less memory copies.

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.

Branches to look

The 'master' branch is where the development of the latest major version lives on. The development of all other major versions takes place in each branch whose name is identical to its major version number. For example, the development of 3.x and 4.x resides in the branch '3' and the branch '4' respectively.
