Downtime

I just came home to find people complaining about lag.
I'm 99% sure I've found the problem, but it'll probably take me a bit to fix. Please expect 15-30 minutes downtime. I apologize beforehand.

I thought I had the problem, but apparently not. Gonna take it down again to let me work freely.

Okay, I think I found the problem. Removing the world/data folder caused the memory usage to drop to about 400MB.
I couldn't find any documentation on what the folder does (google just leads me to people asking where to find the minecraft APPDATA folder is,) but I think it's extra data about the world, mobs/dropped items probably. I'm gonna try looking through the files see if I can find anything abnormal, if anybody has any knowledge about this folder, please do tell.

Here's mine, from a fairly well lived in world (nothing like simplicity ofc but it's been up forever with 3-4 people on it):

Mine's nearly identical, except we also have a Fortress.dat, and we have about 600 maps.
I really wonder why it would make it lag like that.

Probably poorly optimized java code.

Yukar had mentioned that the server was taking up 6 GB RAM at the time, which is way too much.
Did you get a stack dump or java core, Yukar? I'm pretty good with either.

Nuts. Ah well, probably one of the many bugs Mojang introduced to Minecraft with the 1.6.x updates.
