I have been playing on my Minecraft server a lot recently, and we have been making a huge town. Here is a picture:
It only allows up to eight players, and I have ten player whitelisted, so I will be upgrading the server again. Usually, the RAM usage will be about %60 with three people on. It gets very laggy, and it is getting more laggy because it needs to load all the extra terrain when we go exploring, so that is another reason I am upgrading. The house on the left in the water near the jungle is mine (Which happens to be the biggest wood house :D). My brother's (Jonathan, Jehtradedollar) house is behind me, and the track goes to his castle. We have fought the wither on this map too, and it destroyed an entire hill!
