Result: Discarded

The test labeled "md5()" was the faster by 0.0004 seconds, (0.072% faster)

md5() 100%
sha1() 99.928%

The md5() test took 0.561 seconds.
The sha1() test took 0.5614 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 147,647 loops for a total of 2,952,940 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.020) milliseconds per 147,647 loops.
  • Total difference 0.41 milliseconds for 2,952,940 loops

The iteration variablity for Code 1 was (3.6106) milliseconds and Code 2 was (2.5796) 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']);
