activerecord-precompiled

https://github.com/sampokuokkanen/activerecord-precompiled

At deploy time, activerecord-precompiled rewrites simple ActiveRecord query chains in your application source (e.g. `User.where(name: n).first`) into direct calls on the SQLite3 raw connection with SQL generated by ActiveRecord itself. The original expression is kept as a fallback for any case the fast path does not cover.
