I thought I had done both...not seeing any difference in behaviour.

I have several virtual servers operating with php-fpm perfectly fine.
Buffering/caching with Wordpress is great. But now...
I'm trying to implement a new site that uses php for server-side
events to
stream live updates to clients. This is, I believe, properly done
with an
infinite loop in php that will send events as they occur. The problem
is
the events seem to be getting buffered and don't appear.
If I write the php program to end after sending an event then it
works. If
I restart php-fpm then it works - at least for a while.
I've tried numerous config options - obviously what I'm trying isn't
working. Any suggestions?
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.
