PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: md5 vs. sha1

Just to know the speed cost of using sha1() over md5().

Run this test again Return to test menu

Result: Discarded

The test labeled "sha1()" was the faster by 0.0486 seconds, (8.066% faster)

sha1() 100%
md5() 91.934%

The sha1() test took 0.5537 seconds.
The md5() test took 0.6023 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 124,626 loops for a total of 2,492,520 runs.

  • Line execution difference (0.000019) milliseconds.
  • Avg difference (2.429) milliseconds per 124,626 loops.
  • Total difference 48.58 milliseconds for 2,492,520 loops

The iteration variablity for Code 1 was (7.5021) milliseconds and Code 2 was (4.4703) 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']);
