Description

Trying to do the following on macOS Tahoe 26.2 (M4 pro) and it for the first time it's built, the uv add lance-graph command takes a very long time to complete (around 10 mins):

❯ uv add lance-graph --no-cache
Resolved 65 packages in 1.10s
   Building lance-graph==0.4.0
⠦ Preparing packages... (62/63)

Does this end up doing a single-threaded full build of the Rust crates every time it's installed on a new machine? Curious why it's so slow. Once it's installed the first time, the next one is quick because it's in uv's cache. Wondering if there's a way to distribute it with pre-compiled Rust crates for better UX.

Research direction

Start by reproducing uv add lance-graph --no-cache on macOS Tahoe and compare it with a cached install. Inspect the package's Rust build and distribution configuration to determine why first-time installation builds the crates locally. Done means documenting the cause and whether precompiled artifacts can be distributed for a faster first install.
