The test labeled "mt_rand()" was the faster by 0.0465 seconds, (3.668% faster)

mt_rand() 100%
rand() 96.332%

The mt_rand() test took 1.2225 seconds.
The rand() test took 1.2691 seconds.


Each test case ran 20 random code order iterations consisting of 282,159 loops for a total of 5,643,180 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.327) milliseconds per 282,159 loops.
  • Total difference 46.55 milliseconds for 5,643,180 loops

The iteration variablity for Code 1 was (14.9517) milliseconds and Code 2 was (10.5003) 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);
