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 Ry…
