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.
