Photos app grinding my machine to a halt

[AppleGoat]

Hi all,

A few weeks ago, I "upgraded" to High Sierra from El Capitan. I did it the right way. I clean installed it from a thumb drive. For the most part, my machine has run fine. The only problem is the Photos application. A year ago, I invested in a camera and I have since been an avid photographer. I have a ton of RAW files on my machine which I like to view in Photos before editing in Lightroom/Photoshop. Photos, previously known as iPhoto, functioned perfectly on El Capitan but, since I upgraded to High Sierra, my machine slows down significantly whenever the program is open. The UI becomes laggy and frames are dropped, even if I'm not actively doing anything in the application. It's almost as if the program is cataloguing my assortment of pictures (or something).

I would like to get the program to run as smoothly as it had on El Capitan. Any suggestions?

I am running a mid-2014 15" MacBook Pro w/ 16 GB of RAM.

Thanks in advance!
Dan

I had a similar problem, much the same as yours but appeared to be worse: iTunes stopped playing; mouse cursor jumpy; etc. It take a lot to stop iTunes playing! Fixed by added more memory.

Do you have Photos linked up to iCloud?
Could that be causing the problems?

(Don't use iCloud myself, in any way at all)

Thanks for the responses guys.

The first thing I checked was iCloud window and I had unchecked the box for Photos right after installing the OS. So it doesn't appear to be that.

My machine has 16GB and should be able to run an application it ran smoothly in an older OS. I wish I had done a clean re-install of El Capitan. Despite what everyone says, I've never been a proponent of putting new software on older hardware.
