Difference Between Cpu Time And Wall Time at Adam Todd blog

Difference Between Cpu Time And Wall Time. Cpu time, i/o time, and the communication channel delay (e.g. It is the sum of three terms: Wall clock time is exactly what it says, the time elapsed as measured by the clock on your wall (or wristwatch) user cpu time is the time spent in. The main difference between cpu time and wall time lies in what they measure. Wall clock time measures how much time has passed, as if you were looking at the clock on your wall. For example, the host command sends a dns query to a dns server to figure out which mailservers my domain is using: If data are scattered on. Wall clock time is the actual time taken by a computer to complete a task. In order to understand performance you want to compare the two. If what matters to you is the wall clock time, real is the metric to look at. This is the time that your code actually spends executing code on the. User and sys are there to show how long the cpu was actually busy in userland. There's really a few different ways of thinking about time and we're going to look at two here. Cpu time is how many seconds the cpu was busy. Cpu time focuses on the active computation time of the cpu, excluding.

User and sys are there to show how long the cpu was actually busy in userland. The first is cpu time. This is the time that your code actually spends executing code on the. Wall clock time is the actual time taken by a computer to complete a task. For example, the host command sends a dns query to a dns server to figure out which mailservers my domain is using: Many factors can influence how much real time a process takes to complete on a computer: Wall clock time is exactly what it says, the time elapsed as measured by the clock on your wall (or wristwatch) user cpu time is the time spent in. In order to understand performance you want to compare the two. It is the sum of three terms: If what matters to you is the wall clock time, real is the metric to look at.
