Unless you need ultra-low latency, a nothingburger: When retrieving @bsdphk 's benchtime I discovered MarkMail.org died; wanted to evaluate claims made in an article linked by @fanf for not relying on vDSO for POSIX #clock_gettime in contemporary #Linux and #FreeBSD .. It could be rewritten from its very brief functional description in my PhD thesis: "The benchtime program computes the mean [delta] over 2M samples where the ... function has returned an updated value."

Краткое сравнение популярных функций измерения времени
Какую реальную точность можно ожидать от функции возвращающей время, а сколько времени она выполняется сама? Попытка замерить и сравнить несколько десятков функций, доступных программисту на C++. Вот что получилось
