net-speeder is a C-based Linux tool that speeds up single-threaded downloads on high-latency, unstable network links by duplicating outgoing TCP packets to trigger fast retransmission. It uses libnet and libpcap and requires root privileges to run.

Use cases

• speed up single-thread downloads on high-latency links
• accelerate TCP transfers on unstable networks like OpenVZ VPS
• reduce download stalls caused by packet loss
• improve throughput on long-delay cross-border connections

When to choose

• you run a Linux VPS (especially OpenVZ/venet interfaces) with high-latency, lossy connectivity
• you need faster single-threaded downloads and can tolerate doubled traffic
• you want a simple root-run binary with BPF filter rules

When to avoid

• you cannot tolerate doubled outbound traffic and ping-visible packet duplication
• you need a maintained solution - the project sees infrequent updates
• your network is already low-latency and stable, where duplication adds overhead
• you lack root access or cannot install libnet/libpcap
