The test labeled "mt_rand()" was the faster by 0.0035 seconds, (0.483% faster)

mt_rand() 100%
rand() 99.517%

The mt_rand() test took 0.7116 seconds.
The rand() test took 0.7151 seconds.


Each test case ran 20 random code order iterations consisting of 157,207 loops for a total of 3,144,140 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.173) milliseconds per 157,207 loops.
  • Total difference 3.46 milliseconds for 3,144,140 loops

The iteration variablity for Code 1 was (6.0893) milliseconds and Code 2 was (5.8975) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "rand()", was:

$GLOBALS['dummy'] = rand(0, 1000);

The second test, "mt_rand()", was:

$GLOBALS['dummy'] = mt_rand(0, 1000);
