Each test case ran 20 random code order iterations consisting of 287,922 loops for a total of 5,758,440 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.034) milliseconds per 287,922 loops.
  • Total difference 0.69 milliseconds for 5,758,440 loops

The iteration variablity for Code 1 was (5.3809) milliseconds and Code 2 was (4.4747) milliseconds. The lower and the closer together there values are the more accurate the results are.


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