Minecraft is also known to be a memory hog, so it’s important to get a dedicated server with lots of RAM. You should estimate around 8 GB of RAM for every 50 players, but the more the better!
What RAM do I need for my server?
General RAM Recommendations
In general, however, many hosts provide a range of about 16 to 64 gigabytes of RAM for each server. The main thing to keep in mind when it comes to RAM recommendations is that the more applications your server and site will be running, the more RAM you will need.
Does RAM speed affect server?
The more RAM a server has, the less the CPU must read data from the hard disk drive. This means your server may run more quickly since server RAM generally works much faster than a hard disk drive.
Can server affect FPS?
Your framerate is not affected by your internet connection. The things that do affect the framerate are in-game things that are the same on servers as in singleplayer. Servers just tend to have more stuff that lowers your framerate.
