Pausing cart is slower than running in Mindcrack v7

[seattleda]

I've posted a movie explaining the problem. This is on my personal Mindcrack v7 server.

If I ride in a cart, or push the cart, it is very slow. My fps is very high and as a matter of fact, I can run faster than my cart because of its stuttering. Please take a look at the video:

You can really see the problem when I push it along, and then run around to turn off the boarding track. See how it pauses around the corner? And riding, it moves, pauses, moves.

I think the same thing is happening with my quarry. It doesn't run smoothly. Digs four blocks, pauses, digs four more... With 2 generators this was really no problem, didn't notice it as a problem, but with the cart now I think something is messed up. Very sad because I was really looking forward to running highspeed rails into the nether this weekend. Any ideas?

I've tried several things like maxing ram to server, optifine on client... fps is not the issue. Same mod pack in single player doesn't have this problem.

Here is a log of a recent session http://pastebin.com/Cc9cUyW2

IS this in a "clean" world? Or is there stuff built somewhere offscreen?

It looks like typical tick-lag, meaning you've just got too much going on..

 

[seattleda]

so.... how do I reduce the number of things going on? I'm the only one on the server, and from what I can tell, its got decent specs. What have I done to my world? You can see in the log what mods I have installed. This surely can't be happening to everyone with the Mindcrack server?? I've built a 62x62 quarry, researched a little in thaumcraft, built 4 forestry machines and an apiary. (ah, I'll research 'tick-lag' when I get home from work - thanks)

 

[Yeraze]

It's hard to say without more details.. Basically anything that "does stuff" will suck up tick-time.. So if you have lots of Redpower stuff like Timers and such going on, or lots of things flowing through pipes, or massive solar farms (that one has mostly been replaced with Advanced solars stuff), all of that can add lag to the world.

Or you could just be unlucky and have some world-gen oddity that causes it (used to happen occasionally with large water & gravel zones that would take forever to settle).

 

[seattleda]

I don't have any redpower stuff, just a single (large) quarry fed by two fuel engines, fed by dual water pumps. I noticed the lag as soon as I built the quarry - it would go four blocks and pause, four blocks pause, unlike in the tutorial videos where it seems to travel smoothly.

I removed thaumcraft just to see. It did improve the performance of the mine cart, but it did still pause some. Guess I need to radically reduce the number of mods.

I see servers talked about out there that have several users and no lag.... Wish I could wrap up my world and have someone who understands server set ups take a look at it on their machine.

My machine is no slouch. Macpro, 2.8 ghz (8 core) xeon, 10G available. Now, yes, I understand that minecraft itself is single core, so all my cores aren't really going to help. I also moved my mindcrack_server folder to a ramdisk. On the client (a wifi connected laptop, brand new macbookpro) I'm running optifine and getting 30-40 fps) looking at the f3 screen I don't see 100% ticks, just maybe 50% every second or two with the graph green around 25-40%.

I'd be willing to open up my server to public play if someone could help to figure out how to get the cart to travel smoothly. heh Getting from my 'main house' out to the oil field/quarry takes a lot of time. Too bad I can't simply pick up the chunks that I've build stuff on and regenerate my world with an updated set of mods that don't have lag. LOL welcome to minecraft!

If you turn the quarry & associated engines off, does it get smooth?

I tried that, even destroyed the quarry - no, cart was still stuttering every 4-6 blocks, with/without me in it.

I'll work on it tonight, maybe rebuild the world in creative and start adding/removing mods. Can I simply remove all mods and drop my old world into it? I removed thaumcraft and all the thaumcraft items disappeared, so yes, it seems like removing mods is an ok approach.. The idea is that if I can find a stable mix of mods, I can get back into my an old copy of my world without losing too much.

You see the log http://pastebin.com/Cc9cUyW2 that shows all my mods that were running. Yeah, dreams of trying out nuclear power some day AND magic. Haven't even built any other mystcraft or twilightforest worlds either. I'll report back my findings. Would love to hear from others who are running the Mindcrack v7 server and find out what their settup is... Maybe I'll start a thread with that exact topic.[DOUBLEPOST=1358530941][/DOUBLEPOST]

ok i found this in your log file

java.net.SocketException: Broken pipe.............

1. so it looks like Train Craft and forestry are not happy about something

Bob! Yes.... so, uh, how do I fix something like this? (googling 'java reflection' now) thanks

 

[bob marley]

ok good news / bad news
GOD NEWS!!!! I think I found your problem outlined here short version is
TLDR, the server and the clients might need a config file cleanup when this happens. Stop the server/client, delete \.minecraft\config, launch server again.

Bad news you were messing with your config files and something somewhere is not syncing up might have to start from scratch

 

[seattleda]

Thank you Bob! I will try this out tonight! Woot!

Followup - cart is still pausing after a fresh install of v7, but considering there is a 62x62 quarry that's full of water, maybe it'll clear up when the quarry is done and the water drained? Also seeing some weird smp issues, like, if I'm riding away in the cart, my friend sees me just sitting in mid air while I'm saying, no, I've left long ago, until I get to my destination and hop out of the cart, then poof, she says I disappear.

Regarding the errors in the log, after the fresh install, there are still two errors in the log, but they complain about forestry config files, java reflection, etc, so I'm assuming that all v7 servers have this issue, since this was booting the server without my world files.
