SSL/TLS Performance Tuning: TLS 1.3, OCSP Stapling & HTTP/3 QUIC
Reviewed by Cloud Infrastructure & Hosting Architecture Editorial Board
Executive Summary
Eliminating cryptographic handshake latency: 0-RTT session resumption, ChaCha20-Poly1305 vs AES-GCM cipher suites, and UDP-based QUIC transport.
Modern TLS encryption no longer introduces noticeable latency when configured with 1-RTT/0-RTT handshakes, OCSP stapling, and HTTP/3 QUIC transport over UDP.
1. Handshake Optimization Checklist
- TLS 1.3 Exclusivity: Eliminates legacy round trips, establishing encrypted sessions in a single network round trip (1-RTT).
- OCSP Stapling: The web server caches the Certificate Authority's revocation status, preventing client browser DNS/HTTP lookups during TLS negotiation.
- HTTP/3 (QUIC): Replaces TCP with UDP, eliminating Head-of-Line (HoL) blocking on packet-lossy mobile networks.
