Use Argument Clinic for time.clock_gettime() and time.clock_gettime_ns() functions. Benchmark on time.clock_gettime_ns(): import time import pyperf runner = pyperf.Runner() runner.timeit( 'clock_gettime_ns(CLOCK_MONOTONIC_COARSE)', setup='import time; clock_gettime_ns=time.clock_gettime_ns; CLOCK_MONOTONIC_COARSE=6', stmt='clock_gettime_ns(CLOCK_MONOTONIC_COARSE)') Result on Linux with CPU isolation: Mean +- std dev: [ref] 134 ns +- 1 ns -> [change] 55.7 ns +- 1.4 ns: 2.41x faster
