| # Benchmarks |
| |
| Here are some benchmarks, run on an ancient Thinkpad running Intel |
| Core 2 Duo at 2GHz. The input text is a 11MB Markdown file built by |
| concatenating the Markdown sources of all the localizations of the |
| first edition of |
| [*Pro Git*](https://github.com/progit/progit/tree/master/en) by Scott |
| Chacon. |

| To run these benchmarks, use `make bench PROG=/path/to/program`. |
| |
| `time` is used to measure execution speed. The reported |
| time is the *difference* between the time to run the program |
| with the benchmark input and the time to run it with no input. |
| (This procedure ensures that implementations in dynamic languages are |
| not penalized by startup time.) A median of ten runs is taken. The |
| process is reniced to a high priority so that the system doesn't |
| interrupt runs. |
