# Benchmarks

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

Disable the cache by setting the environment variable `GOJEKYLL_DISABLE_CACHE=1`.
Disable threading by setting `GOMAXPROCS=1`.

SASS conversion and Pygments (`{\% highlight \%}`) are cached.

## Jekyll Docs

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.
