Free PHP accelerated software Zend Optimizer performance test

We all know Zend Optimizer This tool is Zend provides a free PHP acceleration software, the official said that this tool can make PHP performance improvement of 30%-40%, I recently personally tried, the Zend optimizer specifically done a test, Discovery can actually improve PHP efficiency. Here is the whole process of testing.

The PHP script used in the test is as follows:

?

To get the current time before the loop starts

$pagestartime =microtime ();

Here we start a loop, just do a simple self increment operation.

$k = 1;

For ($i =1 $i <1000000; $i + +) {

$k + +;

}

At the end of the loop, get the current time

$pageendtime =microtime ();

Calculate the time used for recycling

$starttime =explode ("", $pagestartime);

$endtime =explode ("", $pageendtime);

$totaltime = $endtime [0]-$starttime [0]+ $endtime [1]-$starttime [1];

$timecost =sprintf ("%s", $totaltime);

Print out when to recycle

echo "Times: $timecost";

?>

Test One:

Use Access in the browser, respectively, when Zend Optimizer is enabled and closed: http://localhost/test_zend_opt.php

Enable Zend Optimizer, the execution time for this script is: times:0.117239952087

Close Zend Optimizer, the execution time of the script is: times:0.129501104355

Come to the conclusion that:

When the PHP script is executed, the performance is increased by 9.47% after enabling Zend Optimizer
