High Performance Network Programming on the JVM

Download materials

With support for asynchronous mechanisms such as epoll on Linux, the JVM is a compelling platform for networking applications, striking a good balance between ease of programming and performance. This talk will cover detailed approaches for achieving high throughput and low latency when performing network I/O on the JVM. Treatment will be given to different frameworks for JVM languages including Java (Netty), Scala (Akka) and Clojure (Aleph), synchronous vs. asynchronous I/O and when to use which, as well as other techniques for optimizing throughput and lowering latency. Specific topics will be drawn from practical application building large scale, high throughput messaging systems dealing with millions of mobile devices every second.
