Hello.  I am installing LS on Ubuntu 20.x LTE.  I have installed the LAMP package and am now going through configuring everything.  I have some broad questions that I have not found covered elsewhere.; I have run LS on servers that are in shared spaces, so this is the first time I have had full root access so setting up from default settings.

MPM
The default install is mpm_prefork.  I am guessing that will a couple hundred LS users hitting the server, MPM_mpm_event is a better choice. 

Apache Mods
php7.4 -- yes
session session_cookie session_dbd dbd  -- any of these?
ssl  -- yes
cache cache_disk cache_socache  --  any of these?
others?

PHP+MYSQL
The only program I will be running on this server is LS, so pointing me to any tips on how to optimize the the configuration of these two for the purpose would be most welcome.

Thanks much for your help and support.  CK
