“500~700% performance improvement for basic file copy operations.”
The Rust-based Redox OS keeps plugging away with impressive gains in file I/O performance, better POSIX compliance, and Unix domain socket improvements. A 500 to 700 percent speedup on basic file copies between November 2024 and July 2025 is nothing to sneeze at. They even added a GUI for the kernel debugger. Whether any of this matters outside the hobby OS world remains the open question nobody wants to ask.
