High Performance Template Engine: Guide to optimize your Ruby code

on YouTube ↗34m

" summary

Built two faster Haml engines, Faml and Hamlit, by measuring with benchmark-ips and profiling with stackprof / rblineprof; attribute handling is classified into static, dynamic, and runtime so static HTML can be emitted at compile time. Hot paths get rewritten as C extensions, giving roughly 2x rendering speed in Faml and up to ~18x faster compile-time behavior for Hamlit on some benchmarks after removing expensive features (data-attr hyphenation, boolean attr handling).
