Reducing TTFB with Smarter Cache Strategy

Time to first byte is influenced by application work, caching, and backend responsiveness. Cache strategy is often the fastest lever to improve it safely.

Improvement Areas

• Ensure public pages that do not depend on sessions are eligible for caching.
• Reduce backend work on uncached requests where possible.
• Review whether frequent purges are preventing cache effectiveness.
• Measure the effect of each change rather than assuming the cause.

Performance Discipline

Low TTFB matters most when it improves real user experience consistently. Focus on stable gains across key pages instead of isolated benchmark wins.
