The test labeled "mt_rand()" was the faster by 0.0312 seconds, (3.976% faster)

mt_rand() 100%
rand() 96.024%

The mt_rand() test took 0.7532 seconds.
The rand() test took 0.7844 seconds.


Each test case ran 20 random code order iterations consisting of 161,443 loops for a total of 3,228,860 runs.

  • Line execution difference (0.000010) milliseconds.
  • Avg difference (1.559) milliseconds per 161,443 loops.
  • Total difference 31.19 milliseconds for 3,228,860 loops

The iteration variablity for Code 1 was (6.1388) milliseconds and Code 2 was (5.8482) 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);
