The test labeled "short" was the faster by 0.0504 seconds, (5.367% faster)

short 100%
long 94.633%

The short test took 0.8888 seconds.
The long test took 0.9392 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 248,625 loops for a total of 4,972,500 runs.

  • Line execution difference (0.000010) milliseconds.
  • Avg difference (2.521) milliseconds per 248,625 loops.
  • Total difference 50.41 milliseconds for 4,972,500 loops

The iteration variablity for Code 1 was (1.1726) milliseconds and Code 2 was (1.8860) 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']);
