astral-sh/uv
uv-performance-memory-allocator
crates/uv-performance-memory-allocator/ is a thin wrapper that selects an allocator for the
uv binary at compile time.
Purpose
uv ships with mimalloc on most platforms (and falls back to the system allocator where it
can't be used). The choice of allocator is a measurable resolver speedup, but the build needs
to be platform-aware (musl vs glibc, Windows, macOS). Centralizing the selection here keeps
crates/uv/ clean.
