You are encouraging people to misbehave : ---- http://www.metalinker.org/why.html Metalink was designed for describing the locations of large files that are multi-located (shared via many mirrors and with P2P) so segments can be downloaded from different places at the same time, automatically. ---- Automatic load balancing distributes traffic so individual servers are under less strain. ---- > Can you think of some per transfer and per server options that would help > the situation? As far as I am concerned, either someone uses a single connection to a local/nearby server to download (using segmented download should be use only for failover), or he uses P2P. I will quote Marco d'Itri (cf debian-devel ML last september) : ---- To summarize the issue: * parallel downloads are bad * using P2P when local mirrors are available is very bad ---- François
