Analyzing Bundler Performance: Can Ruby's Package Manager Match uv's Speed?
By

Master baker tier. Every paragraph earns its place on the tray.
Summary
The article explores the performance comparison between Bundler (Ruby's package manager) and uv (a fast Python package installer), examining why Bundler isn't as fast as uv and whether it can achieve similar performance. The author, who was challenged at RailsWorld about this issue, investigates the technical differences between the two tools, analyzes their approaches to dependency resolution and installation, and presents findings from research and a presentation at XO Ruby Portland. The core argument is that Bundler can potentially match uv's speed with optimizations, though there are fundamental architectural differences to consider.
Key quotes
· 4 pulledI firmly believe the answer is 'Bundler can be as fast as uv' (where 'as fast' has a margin of error lol)
Immediately my inner voice said 'YA, WHY CAN'T IT BE AS FAST AS UV????'
At RailsWorld earlier this year, I got nerd sniped by someone. They asked 'why can't Bundler be as fast as uv?'
Since then I've been thinking about and investigating this problem, going so far as to give a presentation at XO Ruby Portland about Bundler performance
