Docker Install on QNAP B2 Slow Upload

QNAP: TS-453D
CPU: Intel Celeron J4125 @ 2.00 GHz (4 cores)
Memory 32GB (Dual Channel Supported)

Decided to use Docker container running the latest version show here:
Image: ghcr.io/linuxserver/duplicati
Duplicati: 2.0.6.3_beta_2021-06-17
No Memory or CPU limitations

I’ve looked in this forum and online to no avail, I have a 1Gbps up/down fiber connection.
I’m seeing a maximum upload speed via Duplicati of around 12 MB/s.

Is there something I can adjust in order to have Duplicati speed up?

Typically my test speeds are:

via speedtest
Download: 907 Mbps
Upload: 937 Mbps
Ping: 1ms
Jitter: 0.11 ms
Loss: 0%

via backblaze speed test
Download: 176.85 Mbit/s
Upload: 56.19 Mbit/s (up to 70 ish)
Ping: 45.10 ms
Jitter: 21.44 ms

Looks like you’re actually exceeding this speed test: 12 MB/s = 96 Mbps

Ok so this seems to be a Backblaze B2 issue.

Thank you

Note that Duplicati processing takes time, you won’t see it saturate a 1Gbps upload link from what I’ve seen.

For what it’s worth, Duplicati running on my Synology 1517+ gets about 5 MB/sec when saving to itself (which later gets uploaded to B2 by Cloud Sync)

Duplicati running on my main PC (i7-6700K) gets about 10 MB/sec when saving to my NAS. My network is 1 Gbps.
