GNU Coreutils 9.11 landed on April 20, 2026, delivering speedups that turn heads in data centers and developer terminals alike. Cat and yes now fly up to 15 times faster on Linux, thanks to zero-copy I/O—a technique that skips unnecessary data shuffling between kernel and user space. Throughput for yes rocketed from 11.6 GiB/s to 175 GiB/s on IBM Power10 hardware, while cat jumped sixfold from 12.9 GiB/s to 81.8 GiB/s there. Even on older AMD Ryzen 7 3700X setups, cat hit 9 GiB/s from 1.67 GiB/s, as detailed in the official release notes on GNU Savannah . Pádraig Brady, the coreutils maintainer, announced the stable release via the project’s mailing list, highlighting 306 commits from 12 contributors over 10 weeks since version 9.10. Top patch authors include Brady himself with 156 commits, Collin Funk at 91, and Sylvestre Ledru with 17—names familiar to those tracking the project’s Git repository.…
