Hi there,
I have the problem on my Minecraft server that I keep having smaller lags or bugging certain things, such as some mobs running faster than they should or taking longer to die. In the WebUI I often get the message "Can't keep up! Is the server overloaded? Running **** ms or *** ticks behind". Are there any specific solutions for how to fix this? We play there with a maximum of 4 players, and I assigned the server 6144M for JAVA_INITIAL_HEAP_SIZE and 9216M for JAVA_MAX_HEAP_SIZE, if this information helps.
