Deathmatch Bundler vs Rubygems.org

on YouTube ↗37m

" summary

The team reimplements the Bundler API, measures with Librato and Papertrail, and scales on Heroku; the result is an index and service that make rubygems.org respond server 100× faster and speed bundle resolution from bundle install 32s → 8s. Postgres outperforms Redis for this workload, moving median app-stack latency ~80ms→20ms and dropping the 95th percentile 600ms → 225ms; external probes reveal 5% external timeouts that drive design choices (Puma deadlocks, Thin/Unicorn tradeoffs, webhooks plus periodic sync, append-only index prototype).
