These scripts may cost more than they're worth

  • www.test.de adds 1028ms and costs ~€11/month
  • cdn-eu.piano.io adds 415ms and costs ~€5/month
  • Unattributable adds 393ms and costs ~€4/month
  • www.test.de adds 347ms and costs ~€4/month

100% of JavaScript execution time is spent on third-party scripts. Consider auditing which scripts are essential.

Why this matters

When third-party JS execution time exceeds your own, performance gains from frontend work are capped by code you don't own.

Learn more ▾

Every millisecond of third-party JS competes with your own for main-thread time. If their share is bigger than yours, optimization on your code base barely moves the needle. Audit, defer, or remove third-parties before further frontend optimization. Use Lighthouse's third-party audit to identify the worst offenders.
