Historical ResultsBased on (1) saved test runs, The test labeled "exec()" was (on average) the faster by 0.0119 seconds, (2.041% faster)
The exec() test took 0.5734 seconds.
The shell_exec() test took 0.5853 seconds.
Each test case ran 20 random code order iterations consisting of 161,599 loops for a total of 3,231,980 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 161,599 loops.
- Total difference 11.95 milliseconds for 3,231,980 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:
