Result: Discarded

The test labeled "sha1()" was the faster by 0.0981 seconds, (7.063% faster)

sha1() 100%
md5() 92.937%

The sha1() test took 1.2913 seconds.
The md5() test took 1.3894 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 127,826 loops for a total of 2,556,520 runs.

  • Line execution difference (0.000038) milliseconds.
  • Avg difference (4.907) milliseconds per 127,826 loops.
  • Total difference 98.14 milliseconds for 2,556,520 loops

The iteration variablity for Code 1 was (16.8680) milliseconds and Code 2 was (15.0645) 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']);
