Lightroom Classic: Problem with previews during import for large volume/slower than LR CC2015.12

LR Classic CC 7.0 Windows 7 w/ATI Radeon 5700
no renaming or presets, minimal previews selected
(1.8 Gb HD with 171 Gb free at the end of this import)

Preview generation/ status update tasks are not quite running in parallel with the file import??:

With an import of 887 D500 photos the library grid display shows blank grid area with "importing files" and the file counters do not change from zero for some time.

After starting the import yesterday for the first time I thought LR had crashed as there was no changes onscreen for about 5min.
However, after cancelling this import and restarting LR I found that there were photos in the destination (not showing in LR though)

Removed photos from the hard drive and started everything again this time I watched the file folder in explorer to see what was going on:

Started import @ 12:36pm
(12:45pm) After 223 photos show up in the destination directory in Windows explorer then LR grid view finally shows 8 thumbnails in the destination folder, the current import collection counter says zero & first sliver of progress appears on the status bar (this is quite late in the process to see first indication of progress)
This continues along until @ 1:14pm the destination directory had all 887 photos in it **.
LR showed only 142 thumbnails and the current import collection counter showed 30, the import process continued on until 1:35pm with all photo thumbnails finally being created.

In the destination folder there were two temporary folders created: "Temporary folder" with a HASH# and "TempParent"
TempParent contained "Temporary folder" with a HASH# folder and a 2nd copy of each of the imported photos
As the thumbnails were finally created these temporary copies were removed.
** When all of the files were copied off the card I still had 600+ extra temp folders so the import was taking almost double the space at this time.

I ran an 2nd import with 66 photos from different card reader and same process exists but thumbnail generation task keeps up better with the import so everything looks ok.
(1st card is XQD, 2nd is SDXC)
I had made several other small test imports with LR Classic to test it and everything seemed normal but this was the first large import.


Ran import with LR CC2015.12 using the same photos and the "TempParent" folder does not appear.
Just the "Temporary folder" and there is at most only one temp photo copy present in that folder while the import runs.
It took just under 4min to import and display thumbnails for 1st 225 photos, thumbnail generation was only at most 40 behind what was imported on disk.
Complete import with previews completed in 14min. So 1/4 time than LR Classic.


For some reason the temp copies/thumbnails are not keeping up in parallel to the import with larger volume imports?
Makes it look like LR crashed when there is no evidence of progress in Lightroom for 5-10min after it starts even though it is working?
And import process takes more disk space than it should.

Hopefully, I explained this ok.

Sure would like to see an answer to this problem.  Literally this make LR unusable for large sessions.  This happens on both of my macs...upgraded per auto updates, and now it sucks to the point of looking at something else.

I am also suddenly having this issue on my laptop. I rolled back from 8.2 to 8.1 and tried also enabling 'Minimal Previews' and disableing generating previews in paralle and nothing works. Lightroom becomes unresponsive and cant even be killed in task manager. If I manage to close Lightroom a backroom process from LIghtroom still runs in the background. Lightroom is unusable like this.

Eu tenho o mesmo problema, mas notei que é apenas para arquivos Nikon d750 (no meu caso), eu trabalho com arquivos 6d e 5d mark III e eles estão importando normalmente

I can't believe there isnt a published solution or official response around this yet. I am seriously considering changing over to Capture1. I'm having to shut down LR (forced close/not responding style) and reload it several times a day because of the seemingly hung (but actually just crazy slow) import.
