This approach was only efficient in the specific case when no change was made (no mark-as-read, favourites, tags), and useless in the other situations. Removed to reduce server load.

While useful for the first request, those preload / prefetch hints are slightly negative for the following requets, especially server-side, e.g. generating one log entry in Apache, and a bit more network traffic.

If it's useless, it's better to remove it completely.

Removed in a666cd8
It might be useful associated with a smarter way of guessing whether the client needs it or not (e.g. first request)

The fast flush optimisation done in FreshRSS#1133 does not seem to work anymore (need to check if it is related to a PHP version). Work-around when PHP flush() is not working Can be tested by adding a `sleep(5);` after: https://github.com/FreshRSS/FreshRSS/blob/ee902ee7c4370421802768c3105ba269a4f97b16/app/layout/layout.phtml#L27 Follow-up of the performance checks of FreshRSS#2040

* Ensure fast flush of HTTP headers and HTML head The fast flush optimisation done in #1133 does not seem to work anymore (need to check if it is related to a PHP version). Work-around when PHP flush() is not working Can be tested by adding a `sleep(5);` after: https://github.com/FreshRSS/FreshRSS/blob/ee902ee7c4370421802768c3105ba269a4f97b16/app/layout/layout.phtml#L27 Follow-up of the performance checks of #2040 * output_buffering in .user.ini for PHP CGI / FPM * Reuse .user.ini for Docker PHP config * Longer flush Flush a bit later, to be compatible with the default value of 4096 for PHP output_buffering, and thus avoid the need of tuning the value.

* Remove next prefetch This approach was only efficient in the specific case when no change was made (no mark-as-read, favourites, tags), and useless in the other situations. Removed to reduce server load. * Remove next prefetch from JavaScript too * Remove some preload / prefetch While useful for the first request, those preload / prefetch hints are slightly negative for the following requets, especially server-side, e.g. generating one log entry in Apache, and a bit more network traffic. * Revert mistake * Remove comment FreshRSS#2040 (comment)
