By default, nginx only starts sending data to a client once it has a full buffer ready. If you want to stream data immediately, you have to switch off buffering - either with the fastcgi_buffering directive, or using the X-Accel-Buffering header in a response. See http://nginx.org/r/fastcgi_buffering for details. Additionally, there are some buffering option in PHP. I'm not a PHP expert, but likely flush() function will help if the problem is on PHP side, see http://php.net/manual/en/function.flush.php. -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
