It helps if you get sleep :) The solution was to disable buffering but since I use php-fpm with apache mod_proxy_fcgi I cannot disable output buffering script wise (maybe I am wrong here?).

So one solution is for apache conf is here: stackoverflow link

Flush packets every 10ms.

# max=10 = 10ms
<Proxy "fcgi://localhost/" enablereuse=on flushpackets=on max=10>
</Proxy>

I don't know the implications of that. But for SSE it works.

So maybe a better solution is here

echo 'SetEnv no-gzip 1' > .htaccess

It seems that those in .php script are useless

@ini_set('zlib.output_compression', 0);
@ini_set('output_buffering', 'off');

because they run AFTER apache?

Now it works with HTTP/2 and HTTP/1.

Thanks @hybrid for the inspiration.
