I need to recheck this again when I get home today, but after the last couple of TT updates, last night I found that my little dispensing station was no longer working. I have an automatic dispensing chest (bukkit plugin) that dispenses an item and a Buildcraft Obsidian pipe used to pick up those items. The problem, is that the Obsidian Pipe is no longer picking up the items. When the items come out of the chest, it looks like something is trying to group them up, then places those items a few blocks away, which is out of reach of the pipe to pick up. The way I got it working for now is to surround the whole area in blocks so that those dispensed items have nowhere to go other than to fall onto the pipe. I have a feeling regardless of how the items are dispenced, the same problem is going to happen (with a dispencer, etc.)
Also, my idle without any players, without any chunk loaders is below 1%. Goes from .7 to 1. When I join, its around 3%, and when I add a few other players, the %'age does not go up... on average, so about 3-4% with a few players. However, when I add a Railcraft "train" with a chunk loader (or just me sitting in the train), the overall usage jumps to an average of 10-12%, and stays there. I have 2 main server based train stations, one east and west, and one north and south. I'm a little unsure why a simple train is using close to 10% of the server, overall and am a little afraid to put up the other North/South train or even let my players use Railcraft. Is it because of the loaded chunks? I'm only showing 550 on average. Any way to have carts force chunks to be unloaded immediately after the trains passes through (might be more of a Railcraft question).
One last thing, is there any way to see how many threads is being used by TT? The config is set to autodetect the threads, but would server as a little piece of mind if I knew TT saw all of my cores.
Everything else is working good.
[Edit] The trains are set to wait for 2 minutes at each station, and even after sitting at the station, the Overall usage still remains @ 10-12%. 10 carts total, 1 Loco, 1 Admin Chunk Loader, and 8 regular carts.
Autodetect just uses as many threads as you have cores.
Can you run `/profile e` after placing a train? Check with `/ticks` that forced chunks actually does increase when using them.
