using the internet add another layer of total complication. you can't
always tell how the packets are being routed, there may be dead
routers, black-hole routers, collissions and dropped packets... all of
which cause a retrans of the missing packet.
The limiter appears to be the internet, it's the slowest speed at 12m.
The internet router at the remote location has to drop the speed from
the 1g to 10m (server to internet) then it has to cross the "great
cloud of routers" <g> to get to you, any one (or more) of which could
be causing trouble.
Have you tested for max packet size and fragmentation on the link? Or
tried cutting the file into smaller pieces to see if it runs any
faster with smaller chunks?
