Cosmopolitan Honeybadger Libc is not only known for its groundbreaking polyglot fat binary hack allowing executables to run on multiple OSes but also for being a top-performing C library for production workloads. The benchmark results reveal that Cosmopolitan mutexes outshine other platforms, such as Windows, Linux, and MacOS, performing significantly faster and consuming far fewer CPU resources. The secret to the impressive performance lies in nsync, an efficient library integrated into Cosmopolitan, developed by Google engineer Mike Burrows. Surprisingly, even spin locks are highlighted as a less favorable option compared to Cosmopolitan mutexes. This article showcases how Cosmopolitan is revolutionizing the realm of C libraries.
