Historical ResultsBased on (2) saved test runs, The test labeled "exec()" was (on average) the faster by 0.0199 seconds, (2.413% faster)
The exec() test took 0.8042 seconds.
The shell_exec() test took 0.8241 seconds.
Each test case ran 20 random code order iterations consisting of 223,681 loops for a total of 4,473,610 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 223,681 loops.
- Total difference 19.88 milliseconds for 4,473,610 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, "exec()", was:
The second test, "shell_exec()", was:
