WebJul 15, 2016 · To measure execution time in C++ using classes from the standard library, follow these three steps: Call high_resolution_clock::now at the start and finish points of the portion of code to be measured. Create an instance of the duration class with the difference between the start and finish time points recorded from Step 1. WebNov 24, 2012 · While a high_resolution_clock may just read a register, a steady clock may need to make a system call to go get the "real" time. If you're measuring very tiny amounts of time (such as profiling the cost of a block of code), then high_resolution_clock is the correct way to go.
