There is no personal data in the report. The full disk access give Etrecheck access to diagnostic reports and additional console logs. Just more data on the state of the Mac.
All I see in the report that I would question is time since boot: 11 days. I'm of the school of rebooting each day to clear out numerous temp caches, swap files, etc. Doing so will help with memory. If you're not into shutting down each night then try booting into Safe Mode, Mac OS X: Starting up in Safe Mode, about once a week.
Where is your library located? If on an external HD how is the drive formatted and connected to your Mac? How big is the library and is it a "managed" or "referenced" library?

As a test launch Photos with the Option key held down and create a new, test library. Import some photos and test to see if the same problem persists. Does it?
