Ruby on Rails Application Serving CS526 Purpose The purpose of this project is to survey the current best application servers for Ruby on Rails, and best methods for reverse proxy to a cluster of application servers. 5.5.2008 Ruby on Rails Application Serving CS526

Ruby on Rails Application Serving CS526 Introduction What is Ruby? Ruby is a dynamically typed object-oriented programming language with significant metaprogramming capabilities What is JRuby? JRuby is an implementation of Ruby that runs on the Java Virtual Machine (JVM) What is Rails? Rails is a web application development framework written Ruby, which uses the metaprogramming capabilities of Ruby to ease development effort. 5.5.2008 Ruby on Rails Application Serving CS526

Ruby on Rails Application Serving CS526 Procedure 1. Set up a basic Rails application (used gullery) 2. Run a single instance of each application server and benchmark the throughput 3. For each of the reverse proxy options: 1. Set up the reverse proxy to dispatch to the cluster 2. Run a cluster of 3 Mongrels, first on Ruby, then on JRuby 3. Run the benchmarks to measure cluster throughput 4. Set up gullery application to run on Glassfish under JRuby and run the same benchmarks 5.5.2008 Ruby on Rails Application Serving CS526

Ruby on Rails Application Serving CS526 Benchmarking All benchmarks performed using RubyWebBench RWB allows scripting requests and weighting among URLs in the application Each cluster setup was tested 3 times with 1000 requests urls.add_url(20, "http://localhost:3500") urls.add_url(40, "http://localhost:3500/projects/show/1") 5.5.2008 Ruby on Rails Application Serving CS526

Ruby on Rails Application Serving CS526 Conclusions Use GlassFish – Combining the reverse proxy with the application server has significant benefit Use Thin on native Ruby, with Apache2 if not JRuby Ruby and JRuby similar overall in terms of performance JRuby takes longer to start, but does better in terms of memory and processor usage JRuby doesn’t have a user-space threading problem 5.5.2008 Ruby on Rails Application Serving CS526
