As it stands now, Windows 8 takes up more bandwidth than earlier versions of Windows.
Alright. This puts you in a position to do two things.
First: you need to back that statement up with actual evidence. The links you posted are to people having bandwidth problems. This does not mean Windows 8 implicitly uses more bandwidth; you can find equivalent posts for any Windows System, going back to at least XP.
Then, you'll have to explain why my observations directly contradict the statement you've made.
A tall order on both counts.
Using a resource needlessly is, by any definition, bad design.
This is yet another false premise. The network transfers performed by Live tiles are done to refresh their display; eg. the Mail Tile would update to show new E-mails. This is no different than already present software; Microsoft Outlook and Windows Live Mail will both do the same thing if kept running.
Also of note is that those Live tile callbacks are not called unless the Start Screen is active.
Some people leave their computers s on all night. So that means every so often live apps will 'ping' home and consume some bandwidth. How much? Little? Very little? Teeny weeny? Curious minds need to know.
The implication here being essentially that no other application that runs on 7 or earlier would ever perform network transfers during idle time.
A foolish and demonstrably false assessment.
Ok so I learned a few things here. Those stuff I was talking about are called "live tiles" and you can disable them. Alright.
If you are on the desktop or running a desktop application they will not update. I don't think they would update when running a window store app, Either.
but he is worried about bandwich consumption once he saw that metro screen on my notebook. He can't speak very well english so he asked me to find some information about this. He thinks those "live tiles" things will make his ms (ping) go higher during online play.
The Live tiles use less bandwidth than pretty much everything else I have running that uses the network. Even when Firefox is sitting and doing nothing it's using 10 times as much as the Live Tiles while they are active.
The Logging I have goes on since I installed my system. The total bandwidth since the 18th of March is a grand total of 50MB used by all my Live tiles.
I find it exceedingly unlikely that Live Tiles would cause network latency.
