I am hosting a Minecraft server on one computer in my house. When one player connects to the server, there is no noticeable latency. When another player also connects to the server, there is a large amount of latency that starts occurring (all in the same network). If I ping my router when only one player is logged in, I get <1ms response every time. If I ping my router when two players are logged in, I get up to 1600ms response time (pinging using command prompt). Is this a bandwidth issue?
There are 8GB of ram allocated to the server.
No one else is using bandwidth other than the two clients connecting to the server.
