Not unusual. All the PHP flush() can do is flush the PHP buffers.
These are sent to the web server, which may do buffering of its own.

It could also be buffered between the web server and the client
application (i.e. server's OS, routers along the way, client OS), but
these are generally very short time and can *usually* be ignored.

When it finally gets to the client, the browser may display the data
immediately, or it may buffer it until some or all of the data comes in
(i.e. HTML tables are often buffered).

All PHP can control is the initial PHP buffers. Everything else is
beyond its control. Since the only thing you changed was your IIS, I
would suggest you look at IIS to see if there's a way to do what you want.
