Result: Discarded

The test labeled "concat" was the faster by 0.0152 seconds, (2.974% faster)

concat 100%
ob_start() 97.026%

The concat test took 0.4953 seconds.
The ob_start() test took 0.5105 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 138,140 loops for a total of 2,762,800 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.759) milliseconds per 138,140 loops.
  • Total difference 15.19 milliseconds for 2,762,800 loops

The iteration variablity for Code 1 was (1.4208) milliseconds and Code 2 was (0.2304) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

ob_start();

for ($i = 0; $i < 100; $i++)
	echo 'Wheat Thins!';

$GLOBALS['dummy'] = ob_get_contents();
ob_end_clean();

The second test, "concat", was:

$value = '';
for ($i = 0; $i < 100; $i++)
	$value .= 'Wheat Thins!';

$GLOBALS['dummy'] = $value;
