Performance ranking¶
As part of its archiving routine, our system conducts routine audits of code quality using Google’s open-source Lighthouse tool. This page ranks the 750 sites with 10 or more observations over the last seven days by median performance score.
The value is the weighted average of a basket of speed and efficiency metrics gathered by Lighthouse. Scores of 90 or greater are considered good. Scores of 50 to 89 are described as needing improvement. Scores below 50 are rated as poor.
This past week the median across all sites was 28. Here’s the distribution of scores:
