Ubuntu 25.10's transition to using Rust Coreutils in place of GNU Coreutils has uncovered a few performance issues so far with the Rust version being slower than the C-based GNU Coreutils. Fortunately there still are a few weeks to go until Ubuntu 25.10 releases as stable and upstream developers are working to address these performance gaps.

  • Well the entire point of the project is that they used algorithms/features of Rust that make it easier to write fast code. This article basically reports on a "bug". Uutils are in many ways already faster than Coreutils.

    Correctness is really more of a byproduct of using Rust. Coreutils have had only a few CVEs in their lifetime so it would be sort of redundant to rewrite them in Rust for "correctness".
