How uv Achieved Its Performance
uv's speed comes from eliminating work rather than optimizing it, with design choices like skipping .egg support and bytecode compilation.
How uv got so fast
nesbitt.iouv’s speed comes from engineering decisions, not just Rust. Static metadata, dropping legacy formats, and standards that didn’t exist five years ago.

Can Bundler 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?” Immediately my inner voice said “YA, WHY CAN’T IT BE AS FAST AS UV????” My inner voice likes to shout at me, especially when someone asks a question so obvious I should have thought of it myself. 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. I firmly believe the answer is “Bundler can be as fast as uv” (where “as fast” has a margin of error lol).
