Wow!
I finally, after watching FS2020 take 3-5 minutes each time I launched it to get to the main screen, installed MSFS Addons Linker. GET IT!! Many of us have many, many addons…scenery, airports, etc. in our Community folder. All of this slows down the loading time considerably as FS2020 reads all those as it loads. With the Linker, you can have only what you need for the current flight. Getting things prepared to use in Linker admittedly did take considerable time. I had to create a bunch of folders, such as SW US flights, NW US flights, Hawaiian Flights, etc. and go through all my Community folder addons to copy or move the respective sceneries and airports in each one. You could get really specific and just have a folder for specific flights between cities/airports but I just generalized. Then I have a folder for my aircraft. Then I created “presets” so that if I want to do a GA flight in the Southwest US I load the SWUS folder and a few GA aircraft I like to use…and so on. After this bit legwork, I renamed my original Community folder so FS2020 won’t see it with all those items in it and created a new, empty Community Folder. When I am ready to sim, I choose the preset I want and launch the sim. My Community folder then has only about a 20th of what it used to have and instead of a 3-5 minute load time I now get about 20 seconds!
Plus the Linker can launch your addon programs, like Little Navmap, etc. automatically.
So, I may sound like salesman here, but since it’s a free priogram I can’t be 
- Get MSFS Addons Linker if you are tired of slow load times. I don’t know if it has other performance advantages but that alone was worth it.
