Does TrueNAS Scale 24.04 limit apps' network speed?

I’ve just converted from Core to Scale 24.04 and having installed the qBittorrent app, I’m disappointed with its download speeds. A torrent which I can download on my desktop at 2.5 MB/s (internet connection about 4.5MB/s, 36Mbps) is downloaded by the qBit app at barely over 1MB/s, with both the desktop and server app using the same settings for transfer rate (unlimited up/down) and number of connections (100 global max, 20 per torrent).

Obviously I’m testing one at a time, not simultaneously, and there are no other devices using a significant amount of bandwidth on my LAN. Is there some throttling I’ve missed in the Scale app settings?

Both the Scale app desktop app (Win 10) are current versions.
