Export Why Is Export Now So Slow?

Lightroom Classic version: 9.3 [ 202005281810-476e492c ]
Operating System
macOS 10.15 Catalina
Since the latest upgrade, exporting even a single file is super slow compared to how fast it was before upgrading to 9.3. It now takes 35–40 seconds (I timed it) for the operation to complete. I have a new, fast Mac, so it's not a hardware issue.

The strange thing is, the "Export n files" progress bar doesn't advance (or advances partway, then stops), and you see the spinning beach ball in Lr (so you can't do anything else), but if you click on the thumbnail that appears on the desktop (if that's your export location) the file is there almost right away.

Exporting multiple files (like two to five) doesn't take a longer or shorter time—it still takes 35–40 seconds.

Neither the export file format (DNG, JPEG, PSD, etc.) nor the size of the exported file (I tried with 600px on the long side all the way up to 24MP, which was the original file size) makes any difference in the time it takes.

Anyone else experiencing this? Any ideas on fixes?

I’ll venture a guess. Lightroom Classic exports uses several threads to export multiple file at once. It also makes use of working storage to create staging temporary file. Working storage utilizes the free space on your primary disk drive. If your primary disk drive is full of nearly so, LrC has to slow down to wait on free space to become available. As a rule of thumb I recommend keeping 100GB or 10-15% of your primary disk drive free for working storage. How much do you have free?

Hey, guesses are welcome. I appreciate your responding. I'm eager to hear if others are finding their Export function is slow, and if anyone has a fix.

Has it always been like this on the new Mac, or has it been faster on this machine?

Thanks for replying, Victoria. It used to be faster on the new machine.

The good news is that the problem is solved. I talked at length with Apple support, thinking it was a Mac problem and not a Lightroom problem, and they had me log out of my Apple account, then uninstall and reinstall the Apple OS. Took about 45 minutes. When I rebooted my Mac and exported images from Lightroom, it was as speedy as before.

I don't know what the conflict was, and it may not be possible to know, but the interaction between Lr and the Mac OS was not functioning properly in some way, and reinstalling the OS fixed it.
