Lightroom Classic: Lightweight export.

This reply was created from a merged topic originally titled Lightroom Classic: Lightweight export. I'm a sports photographer and can end an event with several thousands of photos. I'd like the ability to be exporting one batch while editing the next set in Lightroom Classic. However, the export step hogs up so many resources that I can't effectively edit any more photos until it is done. My computer is reasonably capable and has lots of RAM. It would be nice to have the export feature be something that could run with lower priority so I could still perform edits.

The LR export is a CPU intensive process and in my recent experience, I have discovered that every export in Lightroom Classic (8.3.1) uses all the CPU cores and there is no throttling. It ends up crashing my system. Granted that this could be some problem at my end only because I do not see a lot of people reporting the same problem. 

[Windows 10 OS] I did find a workaround to make sure that the export doesn't consume all the resources on the machine. Just before the export, I went to the system Task Manager > Details > Lightroom.exe and set the affinity so that it doesn't use all the CPU cores. That way, during the export, the system wasn't hitting the 100 % CPU mark and the export finished, leaving enough resources for the other tasks. You can probably use a similar approach to work on a different set while LR exports in the background. it's a hack but it gets my work done while I wait for a permanent fix.
