Benchmark results¶

Recorded 2026-09-21. Historical measurement. Not a measurement of the latest release. Run status: completed.

Which implementation takes less time? Compare every workload with FreeType, the baseline. Lower time is better.

fontdone4 faster · 7 slowervs FreeType · 0 equal · 0 not comparable

Observed median comparisons, not an overall score. Timing-only rows do not establish equal output; small differences may be noise.

Shorter bars = less time within a row. Click a column heading to sort. Scroll the table horizontally on small screens.
