Repairing game takes forever and slows down the pc

I too have been having this problem. 

The first time I noticed it was after the October 6 game update (since I like to repair after every update) and it took hours (6 or more, I ended up going to bed and it was done in the morning). 

I've been avoiding doing any repairs since then, but decided to try again last week and it did the same thing where it used up in the high 90s of my CPU, and I ended up removing most of the packs from the queue (as opposed to cancelling the repair).  I've since uninstalled and reinstalled Origin, I've cleared my Origin cache, I have no mods or cc (I temporarily added the Freelancer Mod fix but that was after the Oct 6 game update and it had been removed before I tried the most recent set of repairs).  I just tried it again after installing some critical updates in Windows and had the same thing happen (and once again cleared most of the packs from the queue). 

The base game plus first few packs seem to go fine, but it starts to slow down around/after pack 5 or so.  That coincides when the CPU usage starts to get to 100%.  Also, even after I clear the queue and it finishes the repair the CPU usage remains high and the only way to get it to go down is to exit Origin.  It goes back to a reasonable level after you exit and start it again (though I had to disable most of the application options to get it to minimal usage while idle). 

Here's a screenshot of Origin and the task manager when it's repairing:

Screenshot of the task manager once the repair has completed (after I removed most packs from the queue); as I commented, I had to close Origin to get that CPU usage to go down (I left it open for a few minutes to see if it would go down on it's own):

I attach my dxdiag as an FYI.
