[BUG] Long Duration for Drive Synchronization without transfers #405
Description
This is the summary of my synchonization with iCloud:
✅ iCloud Sync Complete
📁 Drive:
• Downloaded: 61 files (0 B)
• Skipped: 4652 files (up-to-date)
• Duration: 1h 46m
📷 Photos:
• Albums: all
• Duration: 15m 27s
The synchronization of 100k photos is quite fast (15 min) in comparison to the drive synchronization with 5k files (~2 h), even when in both cases nothing needs to be transfered, because everything already was in sync.
It looks like the checksum calculation or diff mechanism is different between photos and files. Is this intended/known/by design?
Expected behavior
I would expect that the synchronization of photos and drive are comparable.
In my setup icloud-docker runs on a Debian VM on Proxmox host, storing the data on a btrfs HDD-based volume. Monitoring doesn't show any spikes on CPU, memory, network or disk IO during the synchronization.
