What are you talking about? In almost every case I've ever seen or
used, PHP-FPM is *more performant* than mod_php. I work for a company
that writes an absurd amount of complex PHP software. We switched from
mod_php to PHP-FPM everywhere *four years ago* for *performance* and
*stability*. Decoupling the interpreter from the web server improves
the reliability of the stack and makes it easier for code execution
and presentation to perform at optimum levels. Moreover, it becomes
possible to reuse the same FPM instance for multiple applications
across multiple web servers, which is incredibly useful.
Because of FastCGI, php-fpm adds ~1ms to every request, and I'm not the only
one that's measured similar results. Most systems running a web server only
run one webserver, generally either just apache or just nginx, so I don't see
the benefit to that either.

Then just switch everything else. It's not that hard.
Why should I have to switch the system that's being used, and potentially
break these servers, just because a package isn't being compiled anymore? It
still works, and it works very well. It has less overhead than php-fpm, even!

I *just* outlined the problems with shipping mod_php. You can continue
to blithely ignore them at your own peril.
I'm sorry, but I don't see that in the email I'm responding to, the email you
send just before that, or the root of this thread. What are the actual
problems with shipping mod_php? I'm not talking about "benefits" of using
php-
fpm, but the problems with shipping mod_php? I'd be happy to help solve them,
so that users such as myself and the others using mod_php can continue to do
so.
