Above registry modify only take effect on some of my PC, not all of them.
There must be something else affect this.

I think I found a workaround for this issue:
https://www.fixwindowserrors.biz/blog/disable-nagle-algorithm-in-windows-10
Add TcpAckFrequency and TCPNoDelay to registry (to disable TCP_NODELAY) did solve the problem.
So this issue is related to TCP_NODELAY feature.

If this performance issue affects PECL/redis, I suggest that you
file that as issue there; at least the maintainers would become
aware of that, and maybe one of them would have a look at the
issue in the PHP stream layer.
