PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: fcall vs. not (non-trivial)

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "no fcall" was the faster by 0.0129 seconds, (2.375% faster)

no fcall 100%
fcall 97.625%

The no fcall test took 0.5295 seconds.
The fcall test took 0.5424 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 130,836 loops for a total of 2,616,720 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.644) milliseconds per 130,836 loops.
  • Total difference 12.88 milliseconds for 2,616,720 loops

The iteration variablity for Code 1 was (4.4592) milliseconds and Code 2 was (3.4503) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "fcall", was:

/*
function do_something()
{
	for ($i = 0; $i < 20; $i++)
		$GLOBALS['dummy'] + $i;
}
*/

do_something();

The second test, "no fcall", was:

for ($i = 0; $i < 20; $i++)
	$GLOBALS['dummy'] + $i;
