There is no correlation between packets sent and received.
If you are using cable, the "speed" of your downloads is set to a limit by
your cable company (common speeds are 3Mbps and 6Mbps). You will never
achieve the full advertised speeds for several reasons. Also, when using
cable, you are part of a network "node" and you share the available
bandwidth with all other on-line subscribers on that node. You will only
get a portion of the bandwidth available; how much depends on how many are
on-line on your node, the condition of the cable in to your house, etc. In
effect, they advertise a huge bandwidth but in fact deliver much less.
On the other hand, DSL connections deliver the advertised bandwidth all the
time. For instance, if you subscribe to a 3Mbps DSL line, you will have it
all the time. Again, other factors contribute to the fact that you will
generally only get 80 to 90 per cent of your rated speed at the modem, but
you will get it all the time, as opposed to Cable modem, which will slow
down more and more as more users come online. The way that I see it, if I
am going to pay for a service that advertises a rated speed, I want that
speed all the time, not just during off-peak hours. That is why DSL is a
better value..you get your money's worth. I use DSL in my home and am
unaffected by the numbers of users online at my ISP. My neighbor, who has
cable (RoadRunner), which is rated faster than my DSL service, gets about
half the download speed that I get during peak times. He's paying for more,
and getting less. Guess he likes throwing his money away.
