Before I start, let me say that I am in no way affiliated with JBoss or Netty (although I may choose to submit future code as part of the open source community).  Therefore, all comments, code samples, etc are mine or a derivative of examples provided by Netty.   I apologize up front for any possible [...]

Now that I have narrowed by server down to using JBoss Netty, it’s time to define protocols. This involves two things. First, we need to select the actual protocol itself and second, we need to define how to construct the handlers. Let’s start by defining the handlers. Netty is built upon the principle of handlers, [...]

We have now analyzed various open source NIO servers for performance and memory consumption.  Per my quick, initial testing, only Grizzly, Mina, and Netty were comparable. Now, let’s analyze features and how each of these frameworks use them.  For my purposes, I am going to be looking into the following features that I personally value [...]

As my ongoing investigation into picking a suitable and highly scalable server for my future applications, today I will be talking about memory.  Yesterday, we discussed performance and saw in general how Netty and Grizzly compared to one another.  Today, we will further extend that by comparing memory usage footprint at start, over time, and [...]

As a continuation of evaluating an NIO server for my iPhone game, I started with looking at pure performance. First, the following links provide already existant benchmarks: http://swamp.homelinux.net/blog/index.php/2009/03/03/performance-comparison-of-apache-mina-and-jboss-netty/ http://gleamynode.net/articles/2232/ http://mina.apache.org/performance-test-reports.html I took my own samples and quickly ran some basic tests as well to just get a really rough idea.  Note that these metrics should [...]

As part of my new iPhone project to build a new game, I need to have a backend server to communicate with all the members in order to sync and dynamically update on the fly.  Knowing the iPhone and its possibilities, I want to plan for a highly optimistic future in which thousands of concurrent [...]
