The less test took 0.7982 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 209,846 loops for a total of 4,196,920 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.987) milliseconds per 209,846 loops.
- Total difference 19.75 milliseconds for 4,196,920 loops
The iteration variablity for Code 1 was (1.7467) milliseconds and Code 2 was (2.3025) 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);
