Slow preview generation on brand new MBP
When importing (Destination: Current location) photos from my external HDD it'll import about 400 photos in 30 seconds and start generating previews (2560px) and finish in about 5-7mins, while it's generating I check my CPU usage and it's chilln at about 20-30% usage across all cores, and no GPU usage.
So I thought, must be my external drive, so I copied some photos to my internal SSD, and import them, I check how fast it's reading the data from the SSD, about 40-50MB/s (I've tested my SSD and it can read at about 2.5GB/s), so that's not the bottleneck, and the CPU is only doing about 30% (~200% on the C1 process, see dropbox screenshot) so that can't be it. C1 RAM usage is at 2.6GB, with 6GB free, not RAM either. What could it be?
CPU screenshot:
That first peak is importing from my slow external HDD ~400 photos, the 2nd is from my internet SSD ~800 photos, pretty much the same usage both times.

This is on a brand new MacBook Pro (15-inch, 2017), 2.9 GHz i7, 16GB RAM, 512 SSD, Radeon Pro 560 4GB
Capture One 10.2 install from a clean install of macOS. Settings are all default (Hardware Acceleration both set to auto).
Photos are from my Canon 5D (5472 x 3648px), raw photos.
I mean the fans don't even speed up while importing 😜
Am I doing something wrong, or is this the norm?

What's the OS on the MBP?
If it's anything but High Sierra, great question. If it's High Sierra I think you'll need to wait till CO has been certified with it.0 -
On my MBP with basically the same specs except for a 1TB SSD I found that under High Sierra automatic graphics switching doesn't work with C1. I've already notified support about that. Basically it means my system is using the Intel HD Graphics 630 chip instead of the Radeon. In order to use the Radeon, I need to disable automatic graphics switching. You can check which card is being used under  -> About This Mac -> Displays. I don't think it changes a lot with regards to preview generation speed though. It also depends on the camera. My Canon 5DIII files generate previews a lot faster than my Fuji X100F files. 0 -
I'm on High Sierra, and you were right it was using the built-in Intel graphics. I disabled the auto switching and it showed both in the About This Mac, and restarted C1 and imported some more photos and tried editing, to be honest, I see no difference in speed.
I didn't know C1 wasn't updated for 10.13 yet, I'll wait for that then. I guess it could also just be because my camera is a little old now, and they're not optimising for its raw format.0
