Slate is a great code documentation setup based on Middleman. I’ve been playing with it a bit and like it a lot since it’s based on Padrino and very easily extended.
However, I had this problem that every page reload would take roughly five seconds. It turned out the problem is the CSS compilation happening every time I reload.
Since I’m running Ubuntu Linux, I figured I need to use the therubyracer gem.
source 'https://rubygems.org' # Middleman gem 'middleman', '~>4.2.1' gem 'middleman-syntax', '~> 3.0.0' gem 'middleman-autoprefixer', '~> 2.7.0' gem "middleman-sprockets", "~> 4.1.0" gem 'rouge', '~> 2.0.5' gem 'redcarpet', '~> 3.4.0' gem 'nokogiri'#, '~> 1.6.8' gem "sassc" gem 'sprockets', github: 'rails/sprockets' gem "therubyracer"
Suddenly, page reloading was 1.5 seconds.
I then configured Sass to use sassc and grabbed Sprockets from their repository to get a 4.0.0.beta version, as recommended in several issue discussions. That sped up server startup by around 1 second.
