Merb, All you need, nil you don't
summary
Merb claims a lean, benchmark-first redesign: framework code minimizes magic to cut GC churn and keep daemons running for months rather than minutes, and the router covers ~95% of Rails REST features plus UA and deferred routes logic. It uses ParseTree to bind action arguments at boot, returns action values directly, and exposes render_deferred and stream_file primitives to stream S3 objects or background HTTP work without blocking. Everything runs on Rack middleware so you can insert tiny fast API handlers, cascade apps, or swap servers like Thin, Mongrel, EventMachine or E.
