Result: Discarded

The test labeled "md5()" was the faster by 0.0218 seconds, (2.168% faster)

md5() 100%
sha1() 97.832%

The md5() test took 0.9819 seconds.
The sha1() test took 1.0036 seconds.


Each test case ran 20 random code order iterations consisting of 269,383 loops for a total of 5,387,660 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.088) milliseconds per 269,383 loops.
  • Total difference 21.75 milliseconds for 5,387,660 loops

The iteration variablity for Code 1 was (2.6528) milliseconds and Code 2 was (3.8877) milliseconds. The lower and the closer together there values are the more accurate the results are.


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

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

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

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