How to Diagnose a Website That Slows Down When Its Cache Expires

11/10/2026

A cache expiry can trigger many expensive page regenerations at once, causing a temporary load spike and slow responses.

What to check

Compare request latency, cache hit rate, regeneration jobs, database load, and expiry timing. Check whether popular pages expire simultaneously or have no stale fallback.

Recommended next step

Stagger expiry or use safe stale content where appropriate, then monitor response time during refresh. Informatix Systems can investigate hosting performance and caching.
