Tekkit Server Issue (Im A Newbie with light knowledge)

[JoeSmoke]

Hello I am new to the forum, but not new to the gaming community. I have done a load of research and I just cant put a fingure on what is causing choppy out of time gameplay. I want to run a 2 person server for my little brother and I, and I have plenty of power to do so. I just cant figure out the out of time game play. Also I have researched the messge from my server log that says [Warning] Can't keep up, which I am very aware is a server overload. someone please help.

 

My system:

Intel Quad core 2.63Ghz

8GB Ram

30M connection

 

My launch bat:  java -Xmx3G -Xms4GB -jar Tekkit.jar nogui

If you mean that your game is lagging, this is usually an issue with either your connection, your CPU power, or an ingame thing.

 

Connection: Are you playing over LAN or WAN? The latter is also known as Internet. When playing over Internet, many home connections may have insufficient upload data rates, especially during peak times. Even high-bandwidth connections often suffer from absymal upload. There is no fix for this, unless you get a better connection and/or Internet service provider. If playing via LAN, make sure nobody is downloading porn or otherwise taxing the network too much while you play.

 

CPU power: Are you sharing your local game as a server? If so, you may want to move your world to a dedicated server on your network, so your own computer doesn't need to double-task as client and server. Any half-decent dualcore machine that is not older than 6-7 years should be enough for a small two-player server. The dedicated server files can be obtained here.

 

Ingame issues: This can be literally anything, from a glitchy block to a badly-coded mod. See if you can attribute the problem to a specific location in your world. Determine if both of you are having the issues or only one of you. Make sure you are running the recommended Java version, which is the latest Java 7 64bit.

 

That is all I can think of right now.

I thought it was the upload speed as well but I am running a 2 man Vanilla server without a hitch.....Im kinda stumped.....

[Curunir]

Vanilla Minecraft is much lighter on pretty much all resources, including connection. With 100+ mods added, there is simply much more to communicate about.

You could still check if latency or plain bandwidth is the problem.

[JoeSmoke]

0 Latency 30M down 5M up

Vanilla =/= Forge and the upload speed has a tremendous impact on the gameplay.

The Can't keep up messages suggest you have a gamplay/blockupdate problem.

You can try to add opis/mobiuscore to your mods to pinpoint the source of the lag. Check if your render distance changes this behaviour.

For some reason the tracker wont let me start any new topics and i cant get anyone to answer my question but im trying to play on the tekkit modpack and cant find an ip Address can anybody help me out?

The parameters you have configured in the launch.bat don't make sense.

 

-Xms specifies the initial memory allocation pool

-Xmx specifies the maximum memory allocation pool

 

Try the parameters below for your launch.bat. If your operating system, and running processes are heavy on memory you will need to decrease the amount allocated to the java process.

 

java -Xmx6G -Xms6G -jar Tekkit.jar nogui

you haven't played vanilla multiplayer before. IPs don't appear automatically when you choose multiplayer, you need to add the IP from a server manually
