Bug description:stream_socket_client works slower than except
Description:
------------
In my test script, I use two method to create a tcp connection (to
another pc in LAN), one is socket_connect, another is
stream_socket_client.
Since those two code snips doing the same thing, they should have same
time cost.
But on Windows platform, stream_socket_client are must slower than
except.
socket_create are using less 1ms in average,
stream_socket_client are using around 10ms in average.
Can be reproduced from PHP 7.1 to 7.3
Can be reproduced on Windows 2019 & Windows 10 1909.
Test script:
---------------
<?php
$begin = microtime(true);
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_connect($socket, '192.168.163.110', 6379);
$end = microtime(true);
echo ($end - $begin) * 1000 . PHP_EOL;
$begin = microtime(true);
$fp = stream_socket_client("tcp://192.168.163.110:6379");
$end = microtime(true);
echo ($end - $begin) * 1000 . PHP_EOL;
Expected result:
----------------
socket_create & stream_socket_client should use similier time cost
Actual result:
--------------
