Big Sur 11.5.1 on iMac Pro with 64 GB RAM.

Photo library (380 GB) is on a Lacie RAID0 with roughly 300 MBps R/W speeds (HFS+). Opening a photo (doubleckick or Space) takes 8-22 seconds to display the full resolution. These are NOT some insane 100mpix images, just regular iPhone 5-11 Pro photos mostly, with some Canon 6D JPGs thrown in.

Tried rebuilding the library (cmd+opt on startup), didn't fix. Other apps do not have any issue accessing this drive.

Any tips?

Do you by any chance have "Optimize Mac Storage" turned on in "System Preferences, Apple ID"?

Because If it is then the photo has to be downloaded from iCloud first and this will take a few seconds depending on internet speed.

I'm sorry for omitting such a crucial detail. No, it's all local. I only have Photostream enabled. Even with that, it would be weird for a 5 MB photo to take 20 secs to download on my 300/300 mbps connection.

Depends how far and how points it has go through to get to you! Plus it depends how many people are using the server and if it is reaching it’s limited capacity!

Maybe but it's irrelevant, all my photos are locally stored on a fast drive.

have you tried opening the photos in Preview? Also, copy some photos onto your internal drive and create a new library with those photos - same issue?

1) Previews opens full resolution instantly.
2) It does take pretty long time to import the photos (only 450, roughly 12 gigs) to the new library - it took nearly 5 minutes which is kinda insane on a machine of this caliber. CPU was up to 10% used the whole time, Everything is on a very fast, 3 GBps NVMe drive.

But this new library opens full res instanty, as expected. Something's weird.

I don't use Photos, actually use Lightroom ... all my photos are in a folder structure on an external SSD (~ 900MBs r/w), the index is on my internal SSD, browsing thru 1000s of photos is very fast, then opening a photo (RAQ ~ 30MB) is very fast (feels instantaneous) ...
Are your photos in an actual Photos db/library? I'm guessing from your posts and I would further guess that there is some corruption within. Don't know if beyond what you described as "rebuilding the library" in your 1st post there is any other option in Photos to rebuild/re-index?

no, no other option. This is a new issue, I have that library since Photos.app is a thing. I had it on an iMac with a frikkin Fusion drive working flawlessly...

2 options I see:
. contact Apple support
. restore from a backup
