  • Metrics-Powered Ruby/Rails Performance

    by Jeff Casimir

    Ruby can't scale. Tell that to LivingSocial, GroupOn, Gowalla, Sony, and the rest of our community pushing millions of requests per day. Scaling an application isn't about piling up hardware and dropping in the newest database fad, it's the combination of design and refinement.

    In this session, we'll look at refining Ruby code using tools to:

    • Measure memory and object allocation
    • Find CPU-intensive hotspots
    • Isolate data-store bottlenecks
    • Evaluate code complexity

    This is not about info-porn. It's about finding the 1% of your code that, through optimization, can dramatically improve performance.

    At 3:35pm to 4:35pm, Thursday 12th January
