Turborepo 2.9 achieves up to 96% faster performance than Turborepo 2.8, with the gains resulting not from a single optimization but from eight days of combining AI coding agents, Vercel Sandboxes, and conventional engineering practices. The key improvement targeted "Time to First Task" — the overhead of building the monorepo task graph before any work begins — reducing it from 8.1 seconds to 716 milliseconds on the largest tested repository. Throughout the process, a human engineer remained in control, directing profiling strategy and tool selection, with AI agents augmenting — but not replacing — the engineering judgment required to achieve real-world performance gains.
