Bug ID: 501898
Summary: Extremely slow SWLite → SWLite database migration
process to NVME SSD
Classification: Applications
Product: digikam
Version: 8.6.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Database-Migration
Assignee: digikam-bugs-n...@kde.org
Reporter: korwin+kde....@proton.me
Target Milestone: ---
§ STEPS TO REPRODUCE
1. Create a 2.5 GB SWLite database on a (slow) 5400 rpm HDD
2. Run its migration to a (fast) NVME SSD while preserving the database format
§ OBSERVED RESULT
Windows Process Manager shows:
• Source disk usage is around 0-1%;
• Target disk usage is around 95-100%;
• Transfer speed is around 1.5-2.0 MB/s.
§ EXPECTED RESULT
With read speeds from this HDD around 100MB/s, I expect the migration to
complete in a few minutes.

Microsoft Windows 10.0.19045.5608 (22H2)
KDE Frameworks: 6.10.0
Qt: Using 6.8.1 and built against 6.8.1
