І оскільки більшість часу виконання займає реальна робота (а не очікування), а роботу на комп’ютері виконує <abbr title="Central Processing Unit - Центральний процесор">CPU</abbr>, ці проблеми називають «CPU bound».

Поширені приклади «CPU bound» операцій - це речі, що потребують складної математичної обробки.

econds_summary and *_admission_latencies_milliseconds metrics due to reporting wrong unit (was labelled milliseconds, but reported seconds), and multiple naming guideline violations (units should be in base units and "duration" is the best practice labelling to measure the time a request takes). Please convert to use *_admission_duration_seconds and *_admission_duration_seconds_summary, these now report the unit as described, and follow the instrumentation best practices.
