Slow Placing into InDesign From Bridge

Not sure if this is a Bridge question or an InDesign question, but here goes.

I'm using Bridge 8.0.1.282 and InDesign 13.1 on a fairly new iMac with OS 10.13.4. If I select 3 (1-2.5MB jpeg) of around 350 images in a folder from bridge and go to File>Place>InDesign, it takes around 12 seconds before the screen switches from seeing Bridge to when I can see InDesign and the place cursor is ready. When I used earlier versions of Bridge and ID, it took 1 or 2 seconds. I'm working over a network now, but it's the same network as before when it was fast.

Does anyone who places from Bridge to InDesign on a regular basis have this kind of speed? What might I check to get better performance. I updated my InDesign preferences recently (for an unrelated issue), and that had no effect on this.

Any thoughts?
