iMac 5k late 2015
Core I7 4GHZ
AMD Radeon R9 M395X 4GB
500GB SSD Hard Drive
It is a fully spec'd iMac.
the community is crying for a fix for the perforamce issues on High Spec PC/MAC with more than 4 CPUs , lightroom becomes slow after 5 minutes and I need to restart all day + image export become slower after working with lightroom, and if you restart the export is much faster using 100% of the 16 CPUs that I have. This has been reported on several threads see below.
can you check with the development team if they are working on a fix and let us know?
I would be very greatfull if you can do that.
If I tell windows to limit LR to only 2 cores I do see an improvement in operational speeds.
