Result: Saved

The test labeled "md5()" was the faster by 0.0201 seconds, (2.208% faster)

md5() 100%
sha1() 97.792%

The md5() test took 0.8881 seconds.
The sha1() test took 0.9082 seconds.


Each test case ran 20 random code order iterations consisting of 239,880 loops for a total of 4,797,600 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.003) milliseconds per 239,880 loops.
  • Total difference 20.06 milliseconds for 4,797,600 loops

The iteration variablity for Code 1 was (3.1258) milliseconds and Code 2 was (3.0700) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "md5()", was:

$GLOBALS['dummy2'] = md5($GLOBALS['dummy']);

The second test, "sha1()", was:

$GLOBALS['dummy2'] = sha1($GLOBALS['dummy']);
