I know some one who wants to host a moderately large lightly modded(less than 80~ mods, vanilla + type stuff) minecraft server expecting about 50-60 players at max and 15-25 consistent players. The main game play will be more of a building and mod progression type of thing not a pvp smp.
The specs on the pc i use as a standalone server are 
-ryzen 5 2600
-32 gb 3600 ram
-gtx1050
-Samsung 870 QVO SSD
-internet is good enough 700mb up 200mb down

Would it be able to support this if not what would you recommend.
(I would use server optimization mods and preloading chunks.)

Graphics are irrelevant for a server.

According to google, it should support 20-40. I literally asked it "how many players on a lightly modded minecraft server will a ryzen 5 2600 with 32GB ram support?"

Maybe someone with some real world experience has further input. I can say without a doubt that if you run Linux as opposed to windows for the server operating system, you will get better performance and have more resources available to your server.

Thank you for the suggestion if figure that it should be able to support around 40 based on my previous experiences hosting but no one really seems to have a concrete way of figuring it out. You have been alot more helpful than most people and i will probably set up Linux tomorrow.
