3.5x Faster (I bullied Cloudflare into fixing their performance)

Cloudflare improved Workers performance by up to 3.5x after community benchmarks revealed gaps compared to Vercel. The team spent a week fixing scheduling algorithms, V8 garbage collection tuning, stream adapters, and JSON parsing. They also contributed upstream fixes to Node.js and V8 that benefit the entire ecosystem. Key improvements include better cold start handling, reduced memory allocations in OpenNext, and optimized trigonometry functions.
