“Scaling Rails” covers architecture (reverse proxy cache, load balancer, web server, app servers), front-end performance (asset packaging, compression), making SQL fast (database indexes, using EXPLAIN), background processes (cron, queueing), caching (page, action, fragment, SQL, HTTP), load testing (em_proxy), and debugging (New Relic, benchmark,rb, perftools.rb, request-log-analyzer).
