Process slows down over time

Hi, I am testing duplicati on two different systems.

One PC running Windows 10 - SSD drive.

One server running Windows Server 2012R2 - 10k RPM Raid drives.

Backup starts well (average 5 or 6mbs) , after a few minutes, speed decreases to a 500/600kps and real-time logs don’t really show any new activity.

Since this is happening on two completely different systems I would imagine that this is a bug. Is there a way to fix this by tweaking the settings?

Welcome to the forum @ccarminati

Initial backup or incremental which backs up changes? Backup writes use files of default 50 MB size.

Seen how, exactly?

Seen how exactly? If this is a live log, what level? Information shows files, Profiling shows a whole lot.
