Apple Photos app takes incredibly long time to recognize faces

Since I came to Thailand 6 weeks ago, iPhoto on my Macbook pro has been scanning for faces.  On my Mac Pro desktop, this process took about 2 days as I recall.  My iPhone 7 Plus, which I bought a week ago is almost finished.  This time it’s incredibly slow.  I am so sick of seeing this screen:

Picture of Photos app with 18,000 photos remaining to scan.
Wow, only 6,782 photos to go! At the current rate of 100 photos per day, it will take another 60 days at least.

 

screen shot shows iPhone is basically done in less than a week.
iPhone 7 Plus kicks my MacBook Pro’s ass.

I’ve started tracking my progress:

2016-12-22  21:59:  9521 photos left to scan when I quit
2016-12-24  19:04: 16232 photos scanned, 8771 photos left when I quit
2016-12-24  22:14: 16,350 photos scanned, 8653 photos left when I quit
2016-12-26  00:49: 16,352 photos scanned, 8663 photos left when I quit
2016-12-26  19:46: 16,372 photos scanned, 8642 photos left when I quit
2016-12-27  18:29: 16,475 photos scanned, 8574 photos left when I quit
2016-12-28  23:43: 16,707 photos scanned, 8356 photos left when I quit
2016-12-28  23:43: 16,910 photos scanned, 8156 photos left when I quit
2016-12-29  23:51: 17,736 photos scanned, 7332 photos left when I quit
2016-12-30  ??:??: 17,933 photos scanned, 7141 photos left when I quit
2016-12-31  17:34: 18,025 photos scanned, 7064 photos left when I quit
2017-01-01  15:02: 18,307 photos scanned, 6782 photos left when I quit
So there was a burst of speed where it was doing 3,000 photos per day (still not fast, but eventually will finish at that rate), then it slowed to a crawl.

I’ve tried rebooting.  I’ve tried leaving Photos running, and I’ve tried quitting.  Nothing seems to make much difference.  Anybody have this problem and solve it?

  1. Have you asked your question on superuser.stackexchange.com? I was kind of surprised to find out there isn’t an Apple-oriented stack exchange site, but there’re a lot of smart folks on the superuser exchange. On a related note, they also have an expatriates exchange that you might find interesting.

    1. I there is an apple.stackexchange, actually and I had forgotten about it. I’ll ask there, this is disgusting and a feature I used to use frequently but cannot now.
