25Mbps vs 4 Mbps


The service provider(s) pipe that takes all web traffic from my laptop to
the central servers (assume youtube) remain same whether i take a 4Mbps or
a 25Mbps connection from my service provider. This means that the internet
connection that i take from my service provider only affects the last mile
-- from my home network to my service providers first access router. Given
this, would one really see a 6 times improvement in a 25Mbps connection
over a 4Mbps connection?

I assume that the service providers rate limit the traffic much
more aggressively in a 4Mbps connection. But this would only matter if the
traffic from my youtube server is greater than 4Mbps, which i suspect would
be the case.

The question then is that how does going for a higher BW connection from
the service provider help?


That is like asking if a 600 bhp car is 6 times better than a 100 bhp car.

I'd say you definitely can benefit in surfing speed etc up to somewhere 5-15 megabit/s, after that it's hard to discern any difference in interactivity. For youtube alone I doubt you'll notice that much difference.unless you're watching 720p/1080p material, where you will notice that 4 megabit/s probably isn't enough.

I've seen netflix 1080p stream use over 10 megabit/s in 30 second interval, so sometimes it's good to have more :stuck_out_tongue:
