Cloudflare addressed benchmarks that showed Workers slower than Vercel in CPU-heavy tasks. They traced the gap to V8 tuning, scheduling, and inefficiencies in libraries and adapters. Fixes included better isolate scheduling, memory tuning, and optimizations to OpenNext and JSON.parse. They also pushed upstream improvements to V8 and Node.js. As a result, Workers now perform on par with Vercel in most tests and much closer in the remaining ones, while Cloudflare continues to refine performance.
