I've tried several configs over the years and have settled on this setup that allows for default decay and radiation for a 100 player server. The main config file is often referred to as the "CFG" file even though there are several files with the extension CFG like bans.cfg and users.cfg. Depending on your host there may be various ways to modify your server's CFG from command line, simple form field interface like Gameservers and GTX Gaming, to direct editing of the serverauto.cfg under other configurations.
The world size of 4000 tends to be the preferred world size by most players on a 100 player server, but with the new XP grind and longer wipe cycles, it may be prudent to lower world sizes to a range such as 3000-3500 for optimal performance. For reference the default Rust world size is 3000, and I believe this goes into effect if you leave +server.worldsize blank. Learn more about choosing the best Rust map.
Server decay default "1" is recommended for performance reasons. This allows for 100% decay scale and is a good self-cleaning system for especially busy servers. Learn more about why I think Rust decay is a good thing even though there are many players that absolutely hate it.

The Steam Controller
Great controller. Prefer it to Xbox and Playstation controllers. I was a consoler for years before going to pc. As said before, it takes a little bit to get used to, but once you've spent a little time, its amazing for pc.
