Result: Discarded

The test labeled "md5()" was the faster by 0.0133 seconds, (1.513% faster)

md5() 100%
sha1() 98.487%

The md5() test took 0.8689 seconds.
The sha1() test took 0.8822 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 226,504 loops for a total of 4,530,080 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.667) milliseconds per 226,504 loops.
  • Total difference 13.35 milliseconds for 4,530,080 loops

The iteration variablity for Code 1 was (2.2679) milliseconds and Code 2 was (2.6843) 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']);
