Historical ResultsBased on (2) saved test runs, The test labeled "system()" was (on average) the faster by 0.008 seconds, (1.282% faster)
The system() test took 0.6172 seconds.
The shell_exec() test took 0.6252 seconds.
Each test case ran 20 random code order iterations consisting of 159,940 loops for a total of 3,198,790 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 159,940 loops.
- Total difference 8.01 milliseconds for 3,198,790 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.
The first test, "system()", was:
The second test, "shell_exec()", was:
