Bundler has reliably helped the Ruby community install and manage dependencies for close to two decades, but with the announcement of Python's uv we found ourselves asking "Could Bundler be faster?". We took this opportunity to investigate and fix a multitude of performance issues now released in Bundler 4.

In this talk, we’ll dive into why Bundler is slow, what we are doing about it, and how the Ruby community can help. Our goals are to evolve Rubygems and Bundler in order to offer Ruby developers an exceptionally fast experience when running bundle install.
