Technical Impact Analysis

Impact Level:Moderate

Acceptable for most web applications, but may affect highly interactive features

TCP slow start has more impact, connection establishment takes longer, and request waterfalls become more noticeable

Engineering Recommendations

• Optimize TLS handshake with session resumption and OCSP stapling
• Implement HTTP/2 or HTTP/3 to improve connection efficiency
• Use resource hints like preconnect and dns-prefetch
