What is your problem with startup time? Have you timed it? How long does it take?
PHP starts up from scratch on every request, yet it blows Python out of the water performance wise.

I literally gave a timing number in my comment.
The >1 second time was for a very unusual circumstance. Unless you timed PHP startup time using straight CGI (not mod_cgi, nor FastCGI) on a Lustre file system about 15 years ago, with the appropriate set of extensions enabled for what our application needed, you can't really compare the two.

Congratulations.
Now getting back to your request to "Name one", the PHP documentation at https://www.php.net/manual/en/install.unix.commandline.php gives essentially the same answer as I did:
"By default, PHP is built as both a CLI and CGI program, which can be used for CGI processing. If you are running a web server that PHP has module support for, you should generally go for that solution for performance reasons."
PHP is quite slow at encoding and decoding JSON, very slow at any kind of tree data structure, and has among the highest memory usage of any language at printing a string of text to a console or otherwise.
Python is faster at all of those things and it's quite slow. Those are kind of web related tasks, and the web benchmarks for say django vs laravel don't show that PHP is any kind of winner.
I know startup times can take a toll like establishing db connections, cache checking (like redis), file imports, etc. If you are using something that starts up for every request, then you have to be aware of those kinds of things and design around them.
