how many players?

 

40-50 players running on 2/3 worlds with nessescary plugins and a few special ones to differ your server.


Or about 60-70 on a clean install with only nessescary stuff.

 

I have slightly better specs than you, and I manage around 70 with 7 worlds all 1-2gb each!

 

Take a look here, http://canihostaminecraftserver.com - it can give you a rough idea.
It depends on what other services, such as Apache or another webserver you plan to run on it.

I would say about 60 or 70. But it all depends on how your running it

 

I don't think that tool is reporting correctly with 512 gigs of ram you can only get 4 people in a server, The original server I had setup we got well over a dozen on there at once and it didn't have a problem. We have since moved on to a server with more ram dedicated to java and using a ram disk(this part is the important part) and everything ran smoother and we aren't stepping over 4 gigs of ram.
