Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 163,488 loops for a total of 3,269,760 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 163,488 loops.
  • Total difference 15.65 milliseconds for 3,269,760 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.

Code

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

implode('', file('supplement/dummy.inc'));
