Scaling Rails: a system-wide approach to performance optimization
The document discusses improving the performance and scalability of Ruby on Rails applications through a system-wide approach. It outlines goals of creating guidelines, configurations, and patches to optimize all components involved from the operating system to web servers to databases. The methodology involves benchmarking each component, tweaking configurations, testing performance, and developing improvements. The work schedule then details the timeline for researching and improving specific aspects from the OS to Ruby interpreters to Rails frameworks. The overall aim is a comprehensive performance-oriented approach centered around Ruby on Rails.
