Scope
Page performance audit
Measures broader loading and browser performance.
HTTP delivery monitor
Focuses on cache directives, validators, compression, HTTPS and delivery headers.
Comparison
Page performance audit vs. HTTP delivery regression monitor
Why browser performance scores and cache/compression delivery checks solve related but different problems.
Root cause
Page performance audit
A low score can have many causes.
HTTP delivery monitor
Identifies concrete HTTP delivery configuration regressions.
Cadence
Page performance audit
Often run during audits or releases.
HTTP delivery monitor
Designed for recurring baseline comparison after deployments.
Action
Page performance audit
Produces optimization opportunities.
HTTP delivery monitor
Can block or warn specifically when known-good delivery behavior disappears.
Bottom line
Use browser audits for broad performance work. Use an HTTP delivery monitor to protect cache and compression behavior from regression.
QuantMatrix implementation
HTTP Cache, CDN & Compression Performance Auditor
Use this Actor to audit http cache, cdn and compression performance and return structured issues, scores, and remediation signals. Audit public URLs for cache policy, validators, compression, CDN signals, delivery drift and deployment regressions with structured remediation actions.
