Why is it taking ages for Process Recipe to finish?
It's taking an unusual amount of time to process RAW files to small JPGs, around 5 seconds for each one. I'm waiting half an hour to process 200 photos into small JPGs and it gets slower the longer it goes on. I have a modern computer with plenty of processing power, but it's taking ages to process these. Thoughts?
Settings and Computer:
Capture One Pro 9.1
Process Recipe:
• Convert 9MB/22Mega Pixel RAW file to JPG (RAW file folder location is local Fusion Drive disk on iMac)
• Quality 50
• sRGB color space
• 72 px/in
• 800 px long edge
• Save to desktop folder (open none)
• Create thumbnails on save = Unchecked
• Adjustments: Ignore Crop
• Metadata: Include copyright (all others unchecked)
• No Watermark
Computer:
• Late 2013 Apple 27" iMac
• OS 10.11.3
• Processor: 3.2 GHz Intel Core i5
• Memory: 24 GB 1600 MHz DDR3 RAM
• Apple Fusion Drive

iMacs have thermal issues that can cause the GPU to throttle down to protect itself from overheating. I think it's been *mostly* resolved in the current 5K iMacs but it could still be a factor. See what happens if you turn OpenCL off for exporting.
I ran into this when testing a PC video card in my Mac Pro. Not sure if thermal throttling is the issue, but the symptoms are the same. Fast start then gets slower and slower. If I turn OpenCL off then it proceeds at a consistent rate, though slower than it would be if the GPU was able to process all the photos at the starting speed.

Turning off OpenCL for processing seemed to help a bit on the overall speed, but once it gets to about 100 photos it slows back to a crawl. It now only takes about 5 minutes to process out a couple of hundred photos, taking 2 or 3 seconds to processes each one. I might try to wait 15 minutes and see if the computer "cools down" and see if that helps the speed.
I wonder why Phase 1 even keeps that OpenCL around; every time I hear about a problem on here someone is recommending to turn that off.0 -
