Result: Discarded

The test labeled "md5()" was the faster by 0.0358 seconds, (3.037% faster)

md5() 100%
sha1() 96.963%

The md5() test took 1.1426 seconds.
The sha1() test took 1.1784 seconds.


Each test case ran 20 random code order iterations consisting of 287,527 loops for a total of 5,750,540 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (1.789) milliseconds per 287,527 loops.
  • Total difference 35.79 milliseconds for 5,750,540 loops

The iteration variablity for Code 1 was (6.6301) milliseconds and Code 2 was (7.4245) 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']);
