Performance Overhaul

Vercel Workflow now delivers 54% median improvement across server-side performance metrics. Over the past two weeks, the engineering team reduced median API response time from 37ms to 17ms, along with improvements to queue latency, Time to First Byte (TTFB), and per-step overhead.

What Changed

The optimization work benefits all workflows, but especially those that coordinate multiple steps. Since overhead is reduced at each step, the gains compound—meaning complex multi-step workflows see the largest relative improvements.

How to Update

To access these performance improvements, developers should update to the latest version of the Workflow Development Kit:

• Minimum version: workflow@4.1.0-beta.60 or newer
• Installation: npx workflow@latest
• Documentation: Available at vercel.com/docs

Future speedups will be included automatically as the platform continues to evolve.
