I can’t figure out FPM in PHP. As I understand it, FPM can be downloaded only here –
https://php-fpm.org/downloads/ and the last one available is for php 5.2.17 … So there is no FPM for php 7? Or can you rebuild it in some simple way and get php7-fpm? If php 7 cannot be accessed with FPM, then which is faster than php5-fpm or php 7? In short, get my brains right.

Answer 1, authority 100%

Historical information is needed here:

In the project at https://php-fpm.org/downloads/ you see maximum PHP 5.2 binaries because after that FPM was adopted in PHP itself and now exists there. With the status EXPERIMENTAL , the developments were in the PHP 5.3.x branch and already without this mark since 5.4.0 rc2

So you don’t have to choose between PHP7 and PHP-FPM, you’re just trying to search in the wrong place. FPM is alive, healthy and cheerful, and for many years I have not seen projects written in PHP, but not using FPM.

Answer 2, authority 33%

In the context of user experience, performance differences between PHP builds only start to matter in three cases:

1) You have a VERY high-load application (in this case, the question would not arise, as it seems to me)

2) You have a VERY long time to execute a specific script

3) You need optimization for the sake of optimization (it has the right to life, but it is puzzling)

The first case is not considered due to its irrelevance.

I do not consider the third case, since I do not own the load testing data.

The second case is what this site is about. Provide the code (preferably with bottlenecks) and the community will try to help you.

PS Consider this answer more as a question about concretizing your problem. Since there is a high probability that the problem lies somewhat deeper and the specifics will allow us to find a more optimal solution.
