Hi all- I'm running a Direwolf20 FTB Server. We're having somewhat bad problems with chunks not loading. We have the usual chunks filling in in the distance - it's part of the Minecraft experience, right? - but we'll also have chunks failing to fill in even when we're over them, so you get that effect where you can see down into the cave system as you walk/jetpack over them. Sometimes I will be sitting about 2 chunks away and can stare at a group of chunks which will not load even when I face in that direction for a good minute or so.
Here's info about our setup:
Thanks!
Here's info about our setup:
- Running Direwolf20 server, latest. All clients and server up-to-date. Nothing extra added in (except Ticks Per Second, this evening; no noticeable performance change from that)
- OS: OS X 10.8
- Java version: 1.6.0_37
- CPU: Intel Core 2 Duo, 2.6 GHz (Macbook Pro, 2008; Penryn, model T9500). 2 cores, 2 threads
- RAM: 4GB DDR2 667 MHz. We typically allocate 2GB of that to the server.
- Harddrive is spinning rust, 7200 rpm
- Network upload avgs about 7.5 Mbps. The laptop is connected via ethernet cable.
- Not sure if the graphics card is relevant for the server, but: GeForce 8600M GT, 512MB VRAM
- We have 3 players max. Typically 1-2 online ever.
- Command to launch:
Code:
java -server -XX:UseSSE=4 -XX:+UseCMSCompactAtFullCollection -XX:ParallelGCThreads=2 -XX:+UseConcMarkSweepGC -XX:+DisableExplicitGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:+UseCompressedOops -XX:+AggressiveOpts -Xmx2048M -jar direwolf20.jar nogui
- We're not running any Mystcraft ages currently, just Overworld and Nether. Haven't hit The End yet.
- Ticks Per Second (http://www.minecraftforum.net/topic/1548779-1476-ticks-per-second-v0411/) reports 20 TPS for both the Nether and the Overworld.
- I tried running TickThreading (https://github.com/nallar/TickThreading/blob/master/INSTALL.md) which was ... not good. I don't think ticks is the problem really.
- I should say that there is no other obvious lag - no block lag, no chest opening lag or inventory interaction. Mostly the game performs fine, apart from the chunk loading.
- The chunk problem is worst in our base area. The 3 of us have built relatively close to each other, covering probably roughly 12x12 chunks square. I'm running the power and machines, but they're not terribly active unless we have a quarry running. One friend is doing a lot of Forestry stuff (bees and also farms); the other friend is doing a fair bit with Thaumcraft, including using golems.
- It is better away from our base but still not really good at all.
- We have a fair amount of passive mobs in farms (sheep, cows, chickens). Not thousands, but our local E: listing is typically N/170 or so. I did try killing all the passive mobs; this didn't help anything.
- We don't have a lot extra chunk loaded on the server. Basically the quarry does 16 - 25 or so depending on its size, and we have another on a mob grinder which is loading 9 chunks. Otherwise, it's just our spawns.
- This doesn't seem to be connected to our bandwidth speeds or computer power. We have a range of laptops running the client, including a very new Macbook Pro. Our bandwidth is good, generally.
Thanks!
