I'm new at Ubuntu and I'm fiddling around with Ubuntu Server 14.04. I'm trying to get it to run a Minecraft server, but whenever anyone joins, it starts skipping ticks and players reported heavy block-lag.
I checked my RAM with free -m and got the following:
total used free shared buffers cached Mem: 1507 321 1886 0 17 194 -/+ buffers/cache: 109 1397 Swap: 7377 0 7377
The number that I need for my server is 1397. Other than that, a swap ratio of near 1:7 seems a bit much. My question is how I can change these numbers; turn the ratio to a 1:1 and increase my free -/+ (whatever -/+ means).
I'm sorry if this seems trivial to anyone, but I am an incredible noob and I refuse to use PuTTy as I want to learn all the commands. Thanks in advance!
[RE-EDIT] Upgraded 12.04 to 14.04. Bear with me here, people. Thanks in advance.
