More information

Lighthouse sums up the total byte size of all resources that the page requested.

The target score of 1600KB is based on what a page can theoretically download on a 3G connection, while still achieving a time-to-interactive of 10 seconds or less. See googlechrome/lighthouse/pull/1759 for the original discussion.

The 0 to 100 score is calculated from a lognormal distribution.
