Netty framework's event driven interface enables you to write complex, high throughput network applications conveniently. Event driven asynchronous interface enables you to create process bound non blocking network applications of high throughput. Also layered approach that you can adapt by following Netty framework design enables good level of maintainability in your code. Either you are writing a TCP/UDP or a websocket based application you will be following a similar design patterns which are backed by superb documentation. Neety's power really kicks in when you are writing a complex application that will evolve in the future. Maintenance become fairly easy compared to other networking frameworks.

At first getting used to event driven asynchronous approach could be challenging. Specially there are few principles you have to grasp before writing a correct application. At first you can easily write incorrect applications that looks like functioning well. Furthermore, understanding how threading and Netty event loop work is necessary for developing a better application. These are not necessarily bad features, but obstacles before mastering the framework and not by any reason to dislike the framework. Review collected by and hosted on G2.com.
