Camera Raw images take a long time to open in Photoshop CC 2018

[sharkfoot]

I am finding that when I select multiple images in the filmstrip on Camera Raw and click Open Images, it is taking around 30 seconds for each image to open in Photoshop CC 2018. I have the latest version from Creative Cloud installed.

I have an i7-8700k with 32GB of memory, a GTX 1080 ti, and multiple Samsung 960 Pro SSDs. Interestingly enough, I did not have this problem in my last machine build which was an i7 4790k, 16GB of memory, a GTX 1080 ti, and the Samsung 960 Pro SSDs. With that build, the same process would take around 5 seconds per image to open.

The images themselves are 8 bit, 3992 x 2992, 11.9MP at 300ppi. Roughly 24MB per image. My machine should have no trouble opening these up from Camera Raw quickly. Any ideas?

Turns out this may have been due to a Windows updates. Last night an update installed. This morning I tried out the same procedure with Adobe support on the phone and could not recreate the issue. Images are now taking less than half a second to open from ACR to Photoshop.
