Okay, so I went through the process of making the whole mod pack thing, and it's working on the launcher and everything. Now, though, the problem is that the mod pack is causing a lot of people to have a lot of memory and performance issues. I know that now I should probably go into the config files and start trimming the fat in places like disabling or reducing the spawn rate of some things, but I don't even know where to start. Is there some mod that I should prioritize over another, or maybe some way to reduce the heap/permgen requirements for the pack? I know that it's not the number of mods that I have in the pack as there are packs out there with far more mods than I have and they work fine. Here's the link to the modpack page: http://www.technicpack.net/modpack/details/dempaklys.175185

Which mod/config/setting/whatever is making all the "rare" ores (diamond, lapis, redstone, etc.) appear everywhere all the time and at all elevations?
