I tried to reproduce this issue on 4 different environment, 3 environment can reproduce this issue,
1 environemtn can't reproduce this issue.
First I enhanced the test script a little bit, so I can see the overall trend.
https://gist.github.com/vibbow/8909ffc9990023129562e8971fe30f7d
This script will return four number at end of test:
1000 | 0 | 239 | 761
1st and 2nd number are latency below & above 5ms when using socket_create
3rd and 4th number are latnecy below & avobe 5ms when using stream_socket_client
Next is my four enviroment and test results:
- First environment:

Running Windows 10 1909 x64 ï¼Agent A)
Machine Two
Running Windows Server 2019 with Hyper-V enabled (Agent B)

- Second environment:

Machine One:

That'e weird, I can consistent reproduce this issue.
I'll try to replicate my environment on a cloud server and try again.

Hmm, I cannot reproduce this when connecting to another machine on
the same network, where one runs Windows 10 1903 and the other
Windows 10 1909 (tested both directions). Tested with PHP 7.3.11
x64 NTS.

It can also be reproduced on Windows Server 2019

I can get this reproduced on:
Windows 10 1909 x64
PHP 7.3.11 x64 nts
PHP 7.3.1 x64 nts
PHP 7.2.9 x64 nts
PHP 5.6.9 x64 nts
If stream_socket_client connect to a local interface ip address, then everything works fine.
It can only reproduced by connect to another PC on same network.
