Historical Results
Based on (1) saved test runs, The test labeled "include" was (on average) the faster by 0.0081 seconds, (0.804% faster)
The include test took 0.9977 seconds.
The include_once test took 1.0058 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 287,823 loops for a total of 5,756,460 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 287,823 loops.
- Total difference 8.08 milliseconds for 5,756,460 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');
