Why is my download slow, and can I make it faster?
FoxDL splits each file across parallel connections, so most of the time the limit is the server rather than the app. Pro raises the number of simultaneous downloads, the connections per file and the chunk size, which helps whenever the host allows more than one connection.

Three things cap a transfer, in this order: the host’s per-connection limit, your network, and the device. A server that throttles each connection to 1 MB/s is beaten by opening several — which is exactly what the engine does — while one that allows a single connection cannot be beaten by any client.
What to check
- A slow single file, fast everything else — the host is throttling. More connections (Pro) is the only lever.
- Everything slow — the network. Wi-Fi at a distance and congested mobile data both show up this way.
- Fast then slow — a data cap or a shaping rule on the connection, usually per hour or per file.
IPTV downloads are deliberately capped to one connection per file: providers count simultaneous connections against your account quota, and hammering them is what gets an account suspended.
