Hi folks!

Big Rig hasn't been updated for a long time. Over the last years, Chrome Traces format has changed quite a bit, so there's no guarantee Big Rig results are sensible/trustworthy (most likely they're not).

Google Lighthouse is one of the projects that parses Chrome Traces correctly. Since there are a few use cases around that rely on Chrome Traces (including "estimo"), we extracted trace-parsing logic from Lighthouse into a standalone library - Tracium.

Consider using Tracium for a much more trustworthy results.

Thanks!
