Recomended RAM amount for minecraft server

[Lord Nicoll]

So, I've run a minecraft server for me and a few friends for a while. I understand that Hamachi is  probably a bottle neck so that is next after I work out whether I should I should get more RAM. I thought 16GB would always be enough, but more friends of friends (annoyingly) keep coming and it's hard to say no. I was told 16GB should be enough for a good few, I doubt 12 players is that number, but it is DDR 1333 (which shouldn't matter really). I though I'd see what some other techie guys though. I already upgraded the CPU and I doubt it needs an openCL set up.  I doubt more RAM will help, I guess the Hamachi bandwidth is maxed.

 

Edit: The server is running off a dedicated server running Ubuntu Server so I have to tell it how much RAM to use, it has 15.3GB, stop asking about the amount allocated.

How much have you dedicated to the Minecraft server?

 

You should dedicate 3-4GB for optimal performance.

Minecraft is not a ram intense game. 16gb should be enough for 100 players on vanilla, if you have the network bandwidth. A heavily modded game with 12 slots will only consume around 4 gigabytes of ram.

 

Ram speed (1333) should not matter here, that should be fast enough.

16GB is great but it's useless if you don't dedicate it to minecraft server.

 

Cos the minecraft server only uses 200MB by default.

Of coarse, you can find guides for this everywhere OP.

Sorry but I had to say this.

 

If I understand you correctly, what you're asking is "how much dedodated wam for minecraft server?"

 

Seriously though, 16GB is more than enough for what you want. Just make sure you're actually dedicating it to the server. Internet speed is much more important than tons of RAM.

[Lord Nicoll]

Yeah, 15.3GB is actually dedicated. The Xeon x5670x2 handles the heavy workload or not so heavy workload, but I noted something is eating RAM, I don't know, of the 15.3 put to running the minecraft server, about 2GB isn't accounted for. The game version is completely stock, even with no players it's 1.8GB minimum. I might try backing up the files and reinstalling the OS and game, it seemed to take a hit when I moved to RAID 10 from RAID 1. The network is handled by two 1Gb/S Ethernet to my router, which is fibre at 100Mb/s down no matter the load, and 20Mb/s up no matter the load. I think it's the OS and RAID change and Hamachi, I've been meaning to get a new router and get the static IP addon to my internet for a while now.

I cannot not run the Jar file without explicitly allocating RAM in the jar arguments, to which 15.3GB is allocated.

Yeah, i suspect Hamachi is a serious bottle neck, does anyone even like Hamachi? I hate it, everyone who uses it seems to hate it.

Game is stock, but something is using more RAM than it should. It's probably Hamachi with it's bad bandwidth

16GB of dedotated wam is fine for even up to 50 players.

What the fuck is dedotated wam, is it some Linus forum joke for Dedicated RAM?

Never mind I googled it lol

I would never use Hamachi. I always just port forward. It's really not that hard.

Never use Hamachi just wasting bandwidth. Just port forward and you will not have a issue. And ill you need to do is edit this script to your liking and java will use more of the xeons you have.      (Look at the bold)

      This is making the server use 4gb of ram and  allocating it.                                          Change this to how many threads you want java to use

 

java -Xmx4G -Xms4G -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=2 -XX:+AggressiveOpts -jar c1710.jar
pause

 

And save this is a sh of course.

And your good to go.

Currently it is set to use 15Gb, why would I set it to less. The minecraft server for its part uses a fair few of the xeon cores, its not that terrible for only using 1 core (like one program I know)

The reason for hamachi is my current router and internet setup blocks all attempts for players to connect. Its kinda annoying but I'm not going anywhere near the serious networking shit. I have balls and  hence do not posses the required patience to spend 100 year with settings. If something doesn't work how I want it I usually find a hard ware solution.

Again, my router blocks said traffic. Port forwarding does FA. A combination of it being my stock ISP and a dynamic IP is what causes that.
