How Large is the mmaps Folder? Do I need more Database configuration?

Hi, just for a little introduction, I’ve been using CMaNGOS for a while and today I started making a 6.x server; so far it seems to be going well and I’m just waiting on mmaps to finish extracting currently. I’m curious as to how big the mmaps folder should be (just to get a rough idea as to when it’ll complete)? So far, my mmaps folder is 2.8GB and I’m extracting from the latest WoD client (6.2.2a I think).

Edit: mmaps folder is 3.9GB with 8608 items in it. Took 11640639ms (a little over 3 hours) with a FX-8350.

And for the other question, I’m just wondering if I need to do anything else in-terms of database configuration. I manually created the databses (auth, characters, world, hotfixes), and in a bit I plan on importing the TDB_Full DB to world (mistakenly assumed it was included in the git repo). From what I read, does the server handle the initial database import (for all except world) and any database sql updates needed for those 4 databases?
