On my iMac with everything on SSD it works fine. Gathering metadata for 14000 images takes a bit of time, but it works for me. However, if I were using ordinary HDDs or had 100000 images, it would be painful.
I'm also running from my laptop with all images accessed via an smb share over wlan (database on local SSD). In that configuration, performance is extremely slow. It took several minutes gathering the metadata for just the first 2000 images.
And I discovered another issue: Even when i clicked on the Abort button during the gathering of metadata, the gathering of metadata seemed to continue in the background. The dialog box disappeared, but network traffic was still high, and the general performance while continuing my work was poor. So I decided to quit PM+ completely (Cmd-Q), and even that took much longer than normal. Network traffic then went back to normal.
So I have 2 questions/requests:
1) Do you have to access the actual images, rather than just searching the database?
2) Selecting Abort should stop the gathering process, not only dismiss the dialog.
