WEBMay 1, 2010 · 2 Answers. Sorted by: 2. CPU "time" is mostly thought of in clock cycles, or the time it takes the processor to execute its smallest instruction (usually integer addition/subtraction). Other instructions, like ram fetching or floating point divides take multiple CPU cycles. Ram load/store typically take more than 1 clock cycle.

How is CPU time measured on Windows? - Super User
https://superuser.com/questions/723792/how-is-cpu-time-measured-on-windows
WEBThe "CPU time" is the total time used by the program on all CPUs ("CPU" here means "core" if you have hyperthreading disabled; it means "logical processor", if you have hyperthreading enabled). Thus on a system with four cores, HT disabled, a program that runs for 30 seconds of wall-clock time could theoretically use up to 120 seconds of CPU time.

WEBAug 4, 2021 · CPU Time is the time that is actually spent on the CPU. So no I/O time is included in this. For example, if you're doing HTTP requests and each request takes a second to respond, the CPU time doesn't include that second since during that time, we didn't do any CPU work and just waited for the response.

WEBWhat is CPU Time? May 5, 2023 by PerfMatrix. CPU time is the amount of time that the process is using the CPU, converting it to percentage is done by dividing it by the real amount of time passed. For example, if CPU time is 1 second of total execution time 2 seconds then the CPU utilization is ½ x 100 = 50%. How does the CPU time is calculated?
