Vercel Flags SDK Boosts Feature Flag Evaluation 10x
Vercel's Flags SDK now evaluates multiple feature flags in bulk about 10 times faster by reducing microtask overhead and promise creation. The improvement scales with the number of flags, using `evaluate([flagA, flagB])` instead of `Promise.all`. Developers can upgrade to the latest versions to benefit immediately.

A solid performance optimization for feature flag systems, but the 10x claim applies to bulk evaluation—single-flag use cases may see less dramatic gains.
