Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 130,227 loops for a total of 2,604,540 runs.
- Line execution difference (0.000023) milliseconds.
- Avg difference (3.014) milliseconds per 130,227 loops.
- Total difference 60.29 milliseconds for 2,604,540 loops
The iteration variablity for Code 1 was (6.8891) milliseconds and Code 2 was (4.4136) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "more", was:
$GLOBALS['dummy'] = rand(0, 16384);
The second test, "less", was:
$GLOBALS['dummy'] = rand(0, 32);
