Each test case ran 20 random code order iterations consisting of 242,901 loops for a total of 4,858,020 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.937) milliseconds per 242,901 loops.
  • Total difference 38.75 milliseconds for 4,858,020 loops

The iteration variablity for Code 1 was (1.8309) milliseconds and Code 2 was (1.8208) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "file()", was:
