Historical Results

Based on (2) saved test runs, The test labeled "short" was (on average) the faster by 0.0167 seconds, (2.136% faster)

short 100%
long 97.864%

The short test took 0.763 seconds.
The long test took 0.7797 seconds.


Each test case ran 20 random code order iterations consisting of 203,407 loops for a total of 4,068,130 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.000) milliseconds per 203,407 loops.
  • Total difference 16.65 milliseconds for 4,068,130 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "short", was:

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

The second test, "long", was:

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