Historical Results

Based on (3) saved test runs, The test labeled "not" was (on average) the faster by 0.006 seconds, (0.867% faster)

not 100%
ob_start() 99.133%

The not test took 0.681 seconds.
The ob_start() test took 0.687 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 139,962 loops for a total of 2,799,247 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 139,962 loops.
  • Total difference 5.95 milliseconds for 2,799,247 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, "ob_start()", was:

ob_start();

for ($i = 0; $i < 20; $i++)
	$GLOBALS['dummy2'] = $i * 2;

ob_end_clean();

The second test, "not", was:

for ($i = 0; $i < 20; $i++)
	$GLOBALS['dummy2'] = $i * 2;
