In that case, if version 4.71.0 doesn’t fix your issue, it rather indicates a problem specific to your instance rather than an issue related to the update.
I would be curious to see the disk bandwidth usage. An HDD remains quite slow and not necessarily suitable for this type of software like Gladys.
By the way, DuckDB itself states this on its website:
DuckDB’s disk-based mode is designed to work best with SSD and NVMe disks. While HDDs are supported, they will result in low performance, especially for write operations.
