Matthias Einwag 2af04ea2ee Improve WebSocket performance 
Motivation:

Websocket performance is to a large account determined through the masking
and unmasking of frames. The current behavior of this in Netty can be
improved.

Modifications:

Perform the XOR operation not bytewise but in int blocks as long as
possible. This reduces the number of necessary operations by 4. Also don't
read the writerIndex in each iteration.
Added a unit test for websocket decoding and encoding for verifiation.

Result:

A large performance gain (up to 50%) in websocket throughput.

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.
