ramdisk question

Does anyone know how to check if I mounted a ramdisk correctly, and see if its actually being used? I mounted the world files for minecraft a couple weeks ago but I havent seen any noticeable improvement, so I want to make sure that it is mounted correctly. Im using Ubuntu 10.4 LTS this is the outpu...

How to disable Hyperthreading?

I'm on one of the x3470 machines with ubuntu 10.4 LTS and I was wondering if anyone knew how to disable hyperthreading? I'm only running a mysql server and a minecraft server which is entirely single threaded, and what I've gathered from weeks of research is that disabling this feature should improv...

Re: Connection Rate & an off-topic minecraft question

I would assume he meant your connection bandwidth, if so just tell them you're on a 100mbit port as this will never be a bottleneck for you, at least not with minecraft. In regards to authentication, I would not recommend it as it opens up your server to name spoofing, hacking, and all sorts of othe...

Re: Minecraft Error

The error is caused by the authentication servers at minecraft.net being overloaded, though at the moment they appear to be completely down, so trying over and over will do nothing. This happens frequently on weekends, as mojangs infrastructure is simply garbage and their "wing-it" busines...

Re: How Do You Download And Install Java With Fresh Ubuntu 1

If you want to download the Sun java, you will have to un-comment some lines in the sources file to enable partner repositories. Otherwise the apt-get will only find the Open-jdk. This is what I had to do for both my VPS and now my full machine with ubuntu 10.4. I'd post exact steps but I dont remem...

Re: Minecraft process killed on VDS

another upgrade, and now it performs even worse at the new location. No matter how much ram i throw at it, it still lags, and ram doesnt even go past 50% usage anymore after hours running. I read somewhere that customized kernels are sometimes configured in a way that interferes with minecraft, coul...

Server has a hard time keeping up with around 15 players :/ the cpu is locked at 120% most of the time, is that normal?

Re: Minecraft process killed on VDS

what ram amount would you recommend? Im trying to run a 20 player server at the moment, so im looking at lowering it to 2497 or so? that should leave the OS with half a gig to operate (that enough?). I also thought it was 1gb of ram for every 10 players to run smoothly, but i guess not :/

okay my server is getting killed again, even after two ram upgrades :/ should I be safe by disabling the oom-killer? I just dont understand why it wont just slow down or cause lag, instead of killing the server. It would at least give some warning and enough time to react and save map etc. Its getti...
