Here's my setup: PC with AMD A10 5800 cpu and more memory than has

the PC through a 100mbit com port. Is there a way that I can throttle
a given program when it is downloading from the net? The reason I ask
is that yesterday I was downloading the Win10 1809 ISO, and I
basically could not access anything else on the net until that
download finished. Is there someway I can partition the network and
assign a given data stream only a percentage of the total bandwidth?

I have never noticed the effect you describe even with several devices
sharing an internet connection. Obviously they cannot all do a "full
speed" download at the same time but when downloading something like a
Windows iso it is possible to continue browsing etc without any great
problem. This applies even without a super speed connection as the
system shares out the bandwidth.

That was not my experience. When the Windows ISO was downloading, it was
using all available bandwidth. When I tried to access other web pages, most
of the time Firefox would time out with unable to reach server.

I am paying for 7mb/s, but the actual throughput usually measures 5.7mb/s,
which is what was being taken up by the download.
