The Vercel Postgres SDK has significantly improved performance for Postgres queries from Vercel Edge Functions.

The @vercel/postgres package has been updated to use the latest version of Neon’s Serverless driver which adds support for SQL-over-HTTP when you use the sql template literal tag. Simple queries that do not require transactions now complete in ~10ms—up to a 40% speed increase.

You do not need to make any changes to your queries to see these improvements, you only need to update to the latest version of @vercel/postgres to take advantage of these improvements.
