Ridiculous Amount of Lag...

[Iestyn]

Hi there, hope this is the correct place to post this. I've been playing Tekkit for a while, I've got it hosted on my server. I'm using a Mac, I've allocated 4GB of RAM for Tekkit to use but I'm still getting ridiculous amount of lag, especially when I go near any type of quarry or machine, it's getting abosolty stupid, sometimes I'm getting between 1 and 3 FPS.

We get many errors ranging from 'end of stream' to random disconnects. Can someone help me out?

If I haven't provided enough information please let me know

I'm using this version of Java:

java -version

java version "1.6.0_37"

Java SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)

Here's the error log:

i'm having a lot more lag than usual in my single player world too.

[Chefsbrian]

Is the mac hosting the game and playing, or is the server hosted on a separate machine?

Are you running on a Mac too? This is being experienced while playing multiplayer, I don't play single player Tekkit.

Is the mac hosting the game and playing, or is the server hosted on a separate machine?

No, it's hosted on a web server, I've allocated it to have 1024mb of RAM on the server end:

#!/bin/bash

cd "$( dirname "$0" )"

java -server -Xincgc -Xmx1024M -jar ./tekkit.jar

Also using the options button in the launcher itself, I've allocated 4GB from there.

[Chefsbrian]

Well considering that the server gives serious cannot keep up, overloaded errors, I can say it's the server giving issues, not clients. What hardware is the server hosted on?

Yeah but I don't know how much RAM tekkit really needs, it seems to need a hell of a lot more resources than regular, which is ok considering there's a lot more stuff in it, but no where does it tell me how much ram is "recommended to use".

My host is knownhost.com, here's the different VPS packages and I'm on the VPS-3 package:

http://www.knownhost.com/vps_packages.html

How much would you think that tekkit needs? My host is just a regular hosting package, not really intended for gaming, but would you know of a good tekkit host?

Thanks so much for your help :)

[Chefsbrian]

They give good upstream ratings, but no downstream. Ie server does good sending info, not receiving. These are web hosting machines more than game machines from the look. Still, talk to the hosting service, I'm probably wrong XD

[noah Murakami]

I'm running it on a pc

[Chefsbrian]

Noah, don't threadjack, go make your own bug report please. We won't help you here
