Each test case ran 20 random code order iterations consisting of 266,262 loops for a total of 5,325,240 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.777) milliseconds per 266,262 loops.
  • Total difference 15.54 milliseconds for 5,325,240 loops

The iteration variablity for Code 1 was (0.8037) milliseconds and Code 2 was (0.9856) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "include", was:


The second test, "include_once", was:
