Faster CDN proxying to external origins
Vercel optimized connection pooling in its CDN to reduce latency when connecting to external backends, with improvements up to 60% in some regions and 15-30% average latency reduction. The optimization is now live across all deployments at no additional cost.
We’ve optimized connection pooling in our CDN to reduce latency when connecting to external backends, regardless of traffic volume.
This is now live across all Vercel deployments at no additional cost.
