Right, I'll try again. When I'm exporting rom LR Classic 9.3, the CPU usage is going through the roof - so much that I can't even type - the keyboard doesn't recognise half of the keystrokes because the system is running so slowly.. it's awful. It's been getting slow the last couple of versions.. I've just had to install CPU Setter to limit the process in order to be able to edit this post.
It's averaging 500-600% CPU resources, but has peaked at over 800%...
