How to Diagnose a Website That Becomes Slow After a Cache Configuration Change

11/10/2026

A cache change can reduce hit rates, create repeated origin requests, or cache content that should vary by user.

Checks to make

Compare hit and miss rates, origin load, and response timing before and after the change. Check cache keys and bypass rules for authenticated or dynamic content, then test representative routes and users before adjusting TTLs broadly.

When to get help

Hosting support can review cache behavior and origin demand. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
