Summary
This covers the core performance bottlenecks you'll hit with Cloudflare Workers: CPU limits, cold starts, memory pressure, and caching. It's packed with before/after code showing what actually slows things down (unnecessary cloning, buffering entire responses, missing cache layers) and how to fix it. The profiling middleware is genuinely useful for finding hot paths, and the multi-layer caching strategy (memory, Cache API, KV) is solid. Best part is the table mapping errors to fixes, because "CPU limit exceeded" is useless without knowing whether to stream, batch, or optimize your JSON parsing. Aimed at people already hitting performance walls rather than premature optimization.
