Each test case ran 20 random code order iterations consisting of 186,805 loops for a total of 3,736,092 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 186,805 loops.
  • Total difference 4.86 milliseconds for 3,736,092 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.
