Result: Discarded

The test labeled "sha1()" was the faster by 0.0316 seconds, (4.542% faster)

sha1() 100%
md5() 95.458%

The sha1() test took 0.6643 seconds.
The md5() test took 0.6959 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 135,727 loops for a total of 2,714,540 runs.

  • Line execution difference (0.000012) milliseconds.
  • Avg difference (1.580) milliseconds per 135,727 loops.
  • Total difference 31.61 milliseconds for 2,714,540 loops

The iteration variablity for Code 1 was (4.2683) milliseconds and Code 2 was (5.8521) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

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

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

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