Netty Best Practices a.k.a Faster == Better. Netty is one of the most used networking frameworks on the JVM today. Its user base spans individuals to companies like Facebook, Instagram, Twitter, and Red Hat. While its API is pretty easy to use getting the best performance out of it can be a daunting task.
In this talk you will get a short introduction into Netty and how it works, followed by a deep dive to learn more about best practices and optimizations. As part of these optimizations you will learn about some limitations of the current JDK NIO implementation and how we "eliminated" them with our own (optional) JNI based implementation for Linux, using edge-triggered epoll for maximal performance.
