Rendered Speed Signals Check
Review browser-observed loading milestones, resource volume, scripts, third parties, and transferred data.

Slow rendering delays comprehension and interaction. FreeScan uses bounded field-like thresholds to identify obvious page-weight and execution risks, not to replace lab profiling.
Passing evidence
FCP 1.2s · Load 2.4s · 12 scripts · 900KB transferCommon failing evidence
FCP 3.8s · Load 7.2s · 34 scripts · 4.1MB transferPossible false positives
- Local network and third-party response variability affect one run.
- A fast initial load can still hide slow interactions after user input.
How to fix it safely
- Prioritize above-the-fold resources and defer noncritical work.
- Compress images, fonts, and large bundles.
- Remove or delay third-party scripts that do not support the primary task.
How to verify the fix
- Repeat measurements under consistent conditions.
- Confirm improvements in both browser traces and real-user metrics when available.
