Slows down after some edits

Bhanu Pentakota
I use right or left arrows to move the images, and keyboard shortcuts for basic settings. At first, image to image moves very fast but after sometime (May be in 5 to 10 mins or may be after 100 images), it slows down. I can't move fast as it was at first. will have to take break may be around 30 min, come back and continue processing to speed up the process.

I can process 100 images (With basic settings) in 10 min, but 600 images it takes more than 3 hours. Is there anything that I can do to not to slow down the process?

I moved to COP from Lightroom because of same issue but still no luck.

Imac Pro, 32GB RAM, 1TB SSD.

    I know next to nothing about (i)Mac, but your description makes me think in terms of thermal throttling.

    Is a Time Machine backup in progress when this occurs? I find it can slow things down terribly.

    You could do a restart and continue. If it is a memory leak in Capture One, it should be temporarily solved. If it is you hardware overheating, the problem will continue.

    Without doing a deep dive into the logs, my hunch is that it is probably an issue with OpenCL. Turn that off via Preferences > General, Hardware Acceleration, then restart Capture One to commit the change.

    Thank you for your responses. When I am editing on so many images, fans make loud noise and system heat-up. I spend most of the time (Hours continuously) on editing. Not sure if it is normal or an issue. Took appointment with Apple. Will let them diagnose and see if there is an issue.

    No time machine back. When I work COP, I quit all other applications including photoshop.

    I do restart most of the times. as I said, it works faster initially, after some time problem repeats.

    Thank you Ben. I turned off now. Let see how it runs. Will update.
