Officially, no, we don't provide the server configuration. There isn't a standard config that will work well for everyone. Besides, the vendors who provide our requirements already have good documents.
I can recommend the php reference that I use. I go through the entire php.ini, and I generally increase timeouts and max limits quite a bit. For a LAMP that only runs osTicket, I give php as much as 25% to 50% of my available memory and 4GB max file size, etc.
Database optimization: I go through this list and use any that apply to me. Also this is a good guide to improve slow queries (like clicking 'Close'). Likewise, I increase the max memory the database engine can use as much as possible, 50% or more.
