Each test case ran 20 random code order iterations consisting of 282,449 loops for a total of 5,648,980 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 282,449 loops.
  • Total difference 10.62 milliseconds for 5,648,980 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
