Very occasionally you will want to connect directly to the mains (filling a pool) but otherwise the pipe is more that sufficient. Water pipes are sized by pressure drop. You do not want your shower to have fluctuating water pressure if the washer is on while you're there. If you hook up a hose that is the same size as your water main, you can get quite a lot of water at an unacceptable pressure drop, but this may erode the pipe long-term and certainly makes it impossible to shower while you're doing it. Power cables are sized by voltage drop. If the power company sized the wires like they are usually done in houses (just big enough to not overheat and no more) your lights would dim every time you turn any appliance on and you would find it unacceptable. But you could get more power without the cable catching fire if you replaced the main breaker with a bigger one, just watch out for undervoltage and an upset power company. For some reason, it seems some people have problems grasping the idea of having an uncongested path to the Internet even though some of your devices are downloading updates and someone in your family is watching netflix. I wonder if these people leave the tap dripping overnight into a bucket so they can shower while not using more than a few liters per hour? Who would possibly ever need more? And I assume they need to store city gas in a bag to light up their cooker, too. And Tesla's home battery must be the greatest thing since sliced bread. Who would possibly need more than 1-2kW of power per person? Jussi
Re: Re: World's Fastest Internet™ in Canadaland
Good points. But just like I won't take more than one shower at a time, I probably won't watch more than one Netflix stream session at a time (assuming that for myself only). Downloading a large ISO image in seconds is definitely a plus, although at the office I never reach a steady 120MB/s from some Linux mirror out there. I've recently created a Debian mirror and the 1500GB or so of data came at an average speed of 270mbps using a 1gbps datacenter link. I think it will still be a while until we can saturate a 1gbps link inside the average home. While there are people working hard to deliver 1gbps FTTH, there are others working equally as hard in developing video compression algorithms to utilize less bandwidth on the content provider side. Not arguing against it, I'm just throwing gas at the fire to see what different perspectives come out.

Anyone care to comment? Just really curious, as to me it's more of a marketing push than anything else, even though gigabit to the home sounds really cool. Overkill is good provided it doesn't cost too much more. You want the connection speed to not be a limitation on what you are trying to do. 1G does that at a good price point these days. At some point in the future 1G will seem slow and there will be a new speed that stops the link speed being the limitation.

The worry should be over the gigabytes transfered, the kilowatthours and the kilolitres consumed which are the actual resources being delivered. Unfortunately ISP's have made it about link speed rather than what it really is about because link speed was the limiting factor.
