Nextcloud uploads were fine. Just fine. The kind of fine that makes you suspicious.
I’d just gotten gigabit fiber installed, and instead of everything feeling faster, the stack felt the same as it had on the old 5G router line. Browsing the photo library still had a half-beat of lag. Opening Paperless still felt like a coffee opportunity. Either I’d wasted money on the upgrade or something about my architecture was wasting the bandwidth on my behalf.
Spoiler: option two.
