I did not find any recommendation to config a live webserver.
Usually hosting providers have lists for diffrent cms but incomprehensibly, Kirby is rarely represented there.
I’m talking about settings like this:
PDO: Support for using databases
apcu: Support for the Apcu cache driver
exif: Support for exif information from images
fileinfo: Improved mime type detection for files
intl: Improved i18n number formatting
memcached: Support for the Memcached cache driver
zip: Support for ZIP archive file functions
zlib: Sanitization and validation for svgz files
Functions used by Kirby:
exec: for the Imagemagick thumbnail driver
popen: for sending emails through sendmail
there might be others but I didn’t find them with a quick search
