Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.

Why this matters

JavaScript bundle is large — code-split routes and lazy-load off-screen components to defer.

These scripts may cost more than they're worth

  • Unattributable adds 1285ms and costs ~$22/month
  • Microsoft Clarity adds 406ms and costs ~$7/month
  • Google Tag Manager adds 393ms and costs ~$7/month

Unattributable takes 1285ms of CPU time. Consider loading it asynchronously or replacing it with a lighter alternative.

Why this matters

This script has high main-thread execution time — optimize hot paths or defer.

Google Tag Manager takes 393ms of CPU time. Consider loading it asynchronously or replacing it with a lighter alternative.

Why this matters

This script has high main-thread execution time — optimize hot paths or defer.

Source: web.dev

83% of jsDelivr's code is unused. The script may be loading features you don't use.

Why this matters

Bundle has high unused-code ratio — tree-shaking and route-splitting recover the wasted bytes.
