Benchmarking Futexes

Zack’s Kernel News


Chronicler Zack Brown reports on the latest news, views, dilemmas, and developments within the Linux kernel community.

Hitoshi Mitake forked some code that had been originally written by Darren Hart and Michel Lespinasse and produced a new performance-testing subsystem that he submitted as a patch, to be added to the perf bench code in the kernel. Hitoshi’s subsystem was specifically oriented toward benchmarking futexes, a low-level locking mechanism.
