Segmented download is evil... Do you plan to post your ad in all
mirroring lists ?
As I am lazy, I will quote my last answer (FreeBSD mirroring ML) :

As these Metalinks are not officials, would it be possible to remove
ftp.fr.freebsd.org from these files ? I do not want to support nor
promote an "open standard" that encourage software to do parallel
segmented downloads.
I have several problems with segmented downloads. As software open
several connections (it may be several connections on a single server or
single connections on several servers, the result is the same), servers
will serve more connections and will have less memory usable per
connection. As one of the biggest problem on servers is related to disks
IO optimizations, less memory may lead to smaller block reads (and thus
higher disk load). Even if the server has enough memory, as the file are
requested by segments, you are disabling on the server the ability to
fully optimize its disk requests. Last but not the least (and it does
not concern bittorent downloads, only servers), if you do not download
at max speed, it means there is a _real_ bottleneck. It may be on the
server, it may be on the network but speeding up download by using
segmented downloads will not create bandwidth, you will just steal
bandwidth to other people.
