Okay, i got an idea recently to make people make use of their server more efficiently and get a lag free experience
so this is how it works
You can increase the RAM but when you increase the RAM you loose your server's processing power and if you decrease the RAM you can increase the processing power of the server
Example if the server has 2.1GB ram you dont need all of it cuz you are playing a redstone world with your friends where the redstone is complex and heavy and causes your server to lag, so to fix it, you reduce the servers total ram and increase the processing power so now your server runs without lag
The opposite scenario would be that you are running a server where there are lot of people scattered around the map and building stuff this way you dont need the higher processing power so you increase the RAM with the cost of less processing power.
Hopefully this way i can reduce the excess ram and make my server run at more TPS (its usually at 10)
