## Older Versions

## Jekyll Docs (gojekyll 0.2.5)

`[go]jekyll build` on a Late-2015 MacBook Pro, running current versions of
everything as of 2017-07-09.

This site contains only one SASS file.
It contains a few instances of `{\% highlight \%}`.
Each of these results in a call to Pygment. This dominates the un-cached times.

| Executable | Options         | Time   |
| ---------- | --------------- | ------ |
| jekyll     |                 | 9.086s |
| gojekyll   | single-threaded | 5.35s  |
| gojekyll   | multi-threaded  | 2.50s  |
