| Lower numbers are good, higher numbers are bad. A ratio less than 1 | |
| means a speed up and greater than 1 means a slowdown. Green lines | |
| beginning with `+` are slowdowns (the PR is slower then master or | |
| master is slower than the previous release). Red lines beginning | |
| with `-` are speedups. Blank means no changes. | |
| Significantly changed benchmark results (PR vs master) | |
