Historical Results

Based on (17) saved test runs, The test labeled "md5()" was (on average) the faster by 0.0127 seconds, (1.515% faster)

md5() 100%
sha1() 98.485%

The md5() test took 0.8278 seconds.
The sha1() test took 0.8405 seconds.


Each test case ran 20 random code order iterations consisting of 210,087 loops for a total of 4,201,748 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 210,087 loops.
  • Total difference 12.73 milliseconds for 4,201,748 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, "md5()", was:

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

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

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