Description:
------------
On PHP v5.4.x mysqli_connect() and mysqli_query() worked momentally via named pipes for all version
of windows (at least for MySQL v5.5, v5.6, v5.7), but in PHP v5.6.x, v7.0.x, v7.1.x, v7.2.x works
very slowly:
- Windows Server 2008 R2 ~ 50 msec for mysqli_connect()
- Windows Server 2012 R2 ~ 5 msec for mysqli_connect()
I think this is a bug, because in the previous version of PHP everything worked is perfect!
Excuse for bad English.
Test script:
---------------
$time = microtime(true);
$link = mysqli_connect($host, $user, $pass);
$time = (microtime(true) - $time) * 1000;
echo 'Connect = '.$time.' ms.';
$time = microtime(true);
$link = mysqli_query($link, 'select 1');
$time = (microtime(true) - $time) * 1000;
echo 'Select = '.$time.' ms.';
