We’ve optimized connection pooling in our CDN to reduce latency when connecting to external backends, regardless of traffic volume.
Lower latency: Improved connection reuse and TLS session resumption reduce response times by up to 60% in some regions, with a 15–30% average improvement.
Reduced origin load: 97% connection reuse and more efficient TLS resumption significantly cut the number of new handshakes required.
This is now live across all Vercel deployments at no additional cost.
