Measurements

These measurements were made against Active Record 5.2 using an in-memory sqlite3 database. You may run them yourself by cloning this repo and running bundle exec rake bench.

Before running make sure you have run bundle install. This requires the Sqlite3 headers (apt-get install libsqlite3-dev on Ubuntu).
