Filmstrip Lighthouse, mobile

How the page drew during the measured load, at 8 points across 3.00 s.

  1. 375 ms

  3. 1.13 s
  4. 1.50 s
  5. 1.88 s
  6. 2.25 s

Without JavaScript

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

0% of pixels differ — they are identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
