I know this is an old / ongoing thread but I had the same scenario. From acquiring to ready to acquiring etc. And as instructed here, it let it cook outside away from the normal obstructions etc. I don't often have the cycles to devote a lot of time for this, so I didn't let is sit for more than 90 minutes at a time.
There were a few folks here who suggested a longer period of time to build or populate it's tables, especially after a long term storage......4 hrs...that's what it took. Now, when I power up, it's no more than 60 seconds..consistently.
So to all you folks that have traveled this road before me...thank you for passing on your knowledge
