Historical Results
Based on (1) saved test runs, The test labeled "include_once" was (on average) the faster by 0.024 seconds, (3.413% faster)
The include_once test took 0.68 seconds.
The include test took 0.704 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 147,634 loops for a total of 2,952,680 runs.
- Line execution difference (0.000008) milliseconds.
- Avg difference (0.000) milliseconds per 147,634 loops.
- Total difference 24.03 milliseconds for 2,952,680 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, "include", was:
clearstatcache();
include('supplement/dummy.inc');
The second test, "include_once", was:
clearstatcache();
include_once('supplement/dummy.inc');
