Historical Results

Based on (2) saved test runs, The test labeled "short" was (on average) the faster by 0.0068 seconds, (1.439% faster)

short 100%
long 98.561%

The short test took 0.465 seconds.
The long test took 0.4718 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 131,039 loops for a total of 2,620,780 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 131,039 loops.
  • Total difference 6.79 milliseconds for 2,620,780 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.

Code

The first test, "short", was:

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

The second test, "long", was:

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