The test labeled "short" was the faster by 0.0472 seconds, (4.239% faster)

short 100%
long 95.761%

The short test took 1.066 seconds.
The long test took 1.1131 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 288,218 loops for a total of 5,764,360 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.359) milliseconds per 288,218 loops.
  • Total difference 47.19 milliseconds for 5,764,360 loops

The iteration variablity for Code 1 was (2.6323) milliseconds and Code 2 was (4.4864) 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']);
