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:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
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.
