Hi Everyone,

I hope that you can help me with this one....

I just bought a small system to run our MC server with the mod Argarian skies.
This server has the following specs:

AMD a6 6400K (Clocked to 4400)
8 Gig of 1600 Ram
SSD 500-510 read/write
10/120 Mbit Up/Down internet speed

The server keeps saying it cant keep up and in game we have micro stutters.
We are playing on this machine with 4 people in total and are all on 20% of all the quest.
I'm affraid we will not reach the 50% with the stutters already present.

Is it the processor that is just not cutting it or is it in game problems like Itemducts and such?
Please help, i think i just wasted money on nothing.

I think you will need a stronger Server with more RAM. But I'm not sure. But the server does sound relatively weak in the chest. My little DW20 server already runs with 27GB RAM of 128GB. So I think that yours is just too weak.

And sorry of my bad english, I can´t it and use a translator.

Its not my ram, the server is using 600 to 900 Mb and is set to 6 Gb.
The processor should run fine and is fast enough for 4 people.
I agree that its a bit low for more people.

Internuntius, I believe you are wrong sir. RAM is not the issue. Specifically you talked about RAM as a storage space and that leads me to assume you're using something similar to an application called RAMDisk which converts an amount of RAM to store your files. It's very effective but if the computer is turned off, the server is wiped clean from the RAMDisk due to the way RAM functions. Thus backups are needed frequently and stored elsewhere, usually on an HDD.

Anyways for you Umbrix, 6gb RAM on your serverbat file is enormous. More RAM allocation doesn't actually fix issues, moreover it actually creates more issues due to the way Java Garbage Collection (the RAM allocation system governing RAM use in java applications) works. I run a server for 4 other friends as well nowadays and yet I only use 2GB of RAM. I do not use RAMDisk. Also due to the way minecraft is currently programmed with 1.6.4, it does not multi-thread. There are several somewhat-fixing-solutions out there that attempt to make minecraft multi-thread. 1.8 does implement multi-threading, however most mods are not updated to 1.8 yet.

I'm no professional with java, but this is the server.bat file I tend to use when starting my server. Also includes an auto-restart at the bottom there. This should hopefully help. If not, check this site here

Code:
:mine
echo (%time%) Minecraft Server started.

start /B /WAIT java -server -Xms2048m -Xmx2048m -XX:PermSize=256m -XX:NewRatio=3 -XX:SurvivorRatio=3 -XX:TargetSurvivorRatio=80 -XX:MaxTenuringThreshold=8 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:MaxGCPauseMillis=10 -XX:GCPauseIntervalMillis=50 -XX:MaxGCMinorPauseMillis=7 -XX:+ExplicitGCInvokesConcurrent -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=60 -XX:+BindGCTaskThreadsToCPUs -Xnoclassgc -jar FTBServer-1.6.4-965.jar nogui

echo (%time%) WARNING: Minecraft_Server closed or crashed, restarting.
ping 127.0.0.1 -n 20
goto mine

I do not suggest using Ramdisk, especially if you use a SSD. More than capable.
look at your Network usage for me. You only have 10mbit uplink, and with all the mods, that wel get used very fast.

If you wqnt to see if its the CPU, just open the system usage, and look if any cores are used up to 80%-100%
Also, if you run the server on the same PC as you play minecraft, that may actually be the problem. Its just java that has a freaking difficult time on using parallel cores. And if you want to see if your CPU is slow for any reason, since that the Mhz definetly is NOT a way of judging the speed of a CPU, run a SuperPI benchmark.

RAM != performance!, in fact having 27GB of RAM will slow java garbage collection down and cause minor lag.

Check @Greedseed's post above for helpful info on dealing with lag.
