Taking a second look at this i can see where you are coming from about 1 GB of ram not being enough for a 10 player server with 40 plugins but i must argue why do you need 40 plugins? I have a server currently which is private and for testing and has 1 GB of ram and 10 player slots, I have around 12 plugins and that's all i need to make a fully functional server. With my setup i'm able to have 10 players constantly on doing stuff while having no lag at all, I'm always above 19tps and i always have around 300-400mb of ram free.
Hope this helped out. If you have questions feel free to pm me.
