Norman Maurer ffc862dd31 Faster event processing when epoll transport is used
Motivation:

Before we used a long[] to store the ready events, this had a few problems and limitations:
 - An extra loop was needed to translate between epoll_event and our long
 - JNI may need to do extra memory copy if the JVM not supports pinning
 - More branches

Modifications:

- Introduce a EpollEventArray which allows to directly write in a struct epoll_event* and pass it to epoll_wait.

Result:

Better speed when using native transport, as shown in the benchmark.

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

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 versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
