Each route can take up to a few hours to do. Wow. I'm not sure that running the EAGLE autorouter with that fine a grid is good for it. Too much opportunity to misbehave in ways that you don't like. You might be happier letting it run with a coarser grid, which (maybe) could have it leave more unrouted tracks that need manual attention, but less "mis-behaving" tracks that need to be manually modified. But I've never done a board the size of the one you're talking about, so perhaps not...
