Symptoms
Cause
The Download and Upload tiles, the coloured areas of the Traffic card, Quick access and the phone app show only the traffic rtorrent moves to and from its peers. Copies, backups and other programs on the NAS are not included in these figures.
Behind the coloured areas, the Traffic card draws a hatched band showing all traffic on the network interface Rtorrent 16 uses. This includes packet headers and acknowledgements, DHT and trackers, and traffic from every other program on the NAS. A copy to a computer at home crosses that interface but not your internet connection, so the band can show more than your link. Upload with no torrent uploading is traffic in that band.
Each speed figure is averaged over the seconds during which data has been moving: at least 3 and at most the last 60. A new transfer therefore appears within a few seconds. A slow climb depends on the swarm. A new torrent has no peers yet. While downloading, it connects to the peers its trackers return until it has as many as it asks each tracker for: 100 on the Public connection profile and 50 on the Private one by default. Each peer decides when and how much data to send.

- The Traffic card on the Dashboard shows more traffic than your internet connection can carry.
- The chart shows upload while no torrent uploads.
- A new torrent takes a while to reach its full speed.

Resolution
- Read the key of the Traffic card on the Dashboard. Rtorrent 16 is shown in colour; All traffic on … is the hatched band. Point at the chart, or touch it, to read both values at one moment.
- If the band is much wider than the colour, another program on the NAS is moving data: a copy to or from a computer, a backup, a sync job or a media server.
- Compare these figures with your link. On the Dashboard, the Link chart of the Performance card shows Incoming and Outgoing traffic on the same interface, with the link limits from the last test. To measure the link, open Performance, select Link under What to test and press Run test.
- For a slow climb, check the torrent's sources. In Quick access, each row shows how many seeders you are connected to and how many the tracker reports.
Notice & Advise
- During a fast download, the NAS sends acknowledgements at about 1 % of the download speed, so the upload half shows a thin band.
