Ruby is great for scripting, what about the heavy-lifting? In this talk well disassemble the lessons learned at AideRSS, and how weve optimized our Ruby infrastructure to handle millions of RSS feeds on a daily basis building a spider, processing content, and optimizing process coordination and communication. Green Threads and global interpreter lock (GIL) impose a lot of performance constraints on every developer using Ruby 1.8. Well explore the limitations of the MRI, the dreaded global interpreter lock (GIL), and look at the existing and upcoming alternatives Ruby 1.9 concurrency model (Fibers and Actors) & JRuby threading. In similar fashion, well walk through architectural patterns which can help us alleviate these problems: asynchronous and event driven processing, lazy data loading and processing, and common optimization paths for improving performance (ranging from syntactic optimizations, to writing custom C extensions). You dont have to leave the comfort of your Ruby shell to build a high performance system!

About Ilya Grigorik

Ilya Grigorik is the founder and CTO of AideRSS, Inc. After narrowly escaping certain death beneath an avalanche of unread RSS feeds, he knew that something must be done to protect future generations from the menace of information overload, and voila AideRSS was born. An avid Ruby and RoR blogger (for which he received the Ruby Hero award at RailsConf 08), and a tinkerer at heart, Ilya is often found researching or evangelizing the latest web-development practices, software architectures, and web standards in general.
