Resources Files All Reupload Every Time When Publish

Any minor change to the use of any one of my RW Resource files causes all RW Resource files to be reuploaded. That’s a lot of wasted time. I’ve been trying to fix a problem by testing small changes to how a Resource is addressed in my site, and every time I go to Publish I have to wait about 30 minutes to see if I was successful. RW 7.1.7

I could use some help with this. There’s something wrong. There’s no reason RW is reuploading ALL of my Resource files every time.
