# Archived Performance Reports
Legacy release-to-release benchmark comparisons are archived here, including
the last published report preserved before adopting the shared report format.
`docs/performance.md` remains the current report. New complete runs use the
shared history described in [Benchmarking](../../BENCHMARKING.md).
