Purpose

To document performance of ViewComponent, Rails Partials, Dry-View, Trailblazer Cells, Papercraft and Phlex Components.

Benchmarks

Benchmarks arent representative of real life and just render nested components / partials. Take all numbers with a grain of salt.

Contributing

Feel free to submit a PR for optimization of views and other use-cases / view layers.

Setup

git clone https://github.com/paramagicdev/view-layer-benchmarks.git
cd view-layer-benchmarks
bundle install
bundle exec rake benchmark

Benchmarks are for Ruby 3.3.4 and Rails v7.2.
