Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 126,106 loops for a total of 2,522,120 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.807) milliseconds per 126,106 loops.
  • Total difference 16.15 milliseconds for 2,522,120 loops

The iteration variablity for Code 1 was (4.9153) milliseconds and Code 2 was (5.2328) 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'));
