I have to question whether there are any benefits in doing that.
Whether you download files sequentially or out of sync, the server
is trying to do essentially the same thing -- push the same data
down the same physical pipe. Does it matter the order in which it
does it?
Yes, it does matter. There are a number of cases where multiple
connections will win out :
1. avoiding start/finish round-trip delays for each transfer.
You don't of course avoid them - but you can interleave them
with the parallel transfers, and hence keep the pipe closer to full.
2. transient congestion (and packet-drops) have less effect on
multiple connections
Esp. if the congested router is using RED
3. rate-limiting per connection from the server can be imposed
lower than your connection bandwidth
4. bandwidth allocation on congested links
Esp if the upstream router is using WFQ or DRR queuing, and
high capacity connections are severely limited
5. .... many more .....
OK. I yield. :-)
