It collects all tile coordinates for the first level before it starts seeding, so when you start at level 12 and the bounding box is larger, it will take some time to start.
This is not an issue when you start from the top (0-7). We might optimize that sometime.

These are meta tiles. So with a meta size of [4, 4] you have 4096 tiles in 10 seconds, that's very fast.
