There must be something else affect this. ------------------------------------------------------------------------ [2020-01-09 13:58:19] vibbow at hotmail dot com 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. ------------------------------------------------------------------------ [2020-01-02 16:32:03] cmb@php.net 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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
