Internet Service Providers (ISPs) often use to identify BitTorrent traffic and intentionally slow it down to preserve bandwidth for other users.
Speeds start fast for the first few minutes and then plummet and stay low. The Fix:
In your client's settings (e.g., uTorrent or qBittorrent), set Outgoing Protocol Encryption to "Forced" or "Enabled." This makes your traffic harder for the ISP to identify.
A fluctuating BitTorrent download speed is rarely caused by a single issue; rather, it is often a combination of hardware bottlenecks, software misconfigurations, and network interference.
A reputable VPN for torrenting encrypts all data leaving your computer, preventing the ISP from seeing what you're doing and stopping them from throttling specific activities. 2. Hard Drive Bottlenecks (Disk Overload)
