The Neon serverless Postgres driver has reduced the latency of connections by cutting network round-trips in half. It achieves this by redirecting the PostgreSQL TCP wire protocol over WebSockets, eliminating the need for a separate WebSocket-to-TCP proxy. The driver uses TLS 1.3 to establish connections and eliminates unnecessary round-trips such as the `SSLRequest` message exchange. Additionally, it has improved Postgres authentication speed by using simple password auth instead of SCRAM-SHA-256, and pipelining Postgres interactions to reduce round-trips. With these improvements, the driver now achieves a total of four network round-trips, which is the lowest possible with current technologies. The team hopes to further optimize performance with WebSockets over QUIC in HTTP/3 and pipelining independent queries in Postgres.
