Super slow scanning in Syncthing

I recently installed this container on a Pi 4 2GB which has openmediavault 5 on it. I set it to scan a folder which contains 3.5GB of files and it has taken over 2 days to scan. Is this normal?
I checked CPU usage and it is less than 1 percent. Ram is at 50mb. Also, disk access is occurring but only in spikes every so often.
