Wicked Fast Development with Zeus28 Dec 2012
rake routes = 4.69s
rake routes = 0.34s using zeus gem
I work on a large Rails app for my full time gig. The startup time for the Rails stack is about 20 seconds (aka, 20 seconds too long). This was especially cumbersome when doing TDD-development.
We tried leveraging Spork and Watchr (similar to Rspec-Guard) to more efficiently manage the Rails stack env. These were great tools. But our configuration required us to restart spork/watchr after we had changed a Rails environement constant or symbol (EG, Ruby class, FactoryGirl factory, spec file).
solution = zeus
Then we found zeus.
Zeus loads and re-loads your Rails environment as needed (like when Rails constants or symbols change) so you are guaranteed to have a fresh Rails environment ready at your command to run RSpec, migrations, rake tasks or etc.
And here’s an example app.
cd git gem install rails gem install spree # spree requires rmagick (gem), which requires imagamagick (os) rails new example_zeus spree install example_zeus cd example_zeus time rake routes # rake routes 4.69s user 0.42s system 99% cpu 5.117 total ### using a MacBook Pro, 16GB RAM, 256GB SSD echo "gem 'zeus'" >> Gemfile bundle install zeus init zeus start # in a new shell window cd git/example_zeus time zeus rake routes # zeus rake routes 0.34s user 0.03s system 32% cpu 1.136 total ### while using a MacBook Pro, 16GB RAM, 256GB SSD
Happy zeus-ing :)
