More people surfing the net slow my internet speed?

The internet is a series of tubes. And when you start dumping too much stuff in these tubes, they get all clogged up.

no surfing (unless they are going to some huge pages and refreshing every second) should not slow down your internet connection. unless you have like 50 + comuters surfing at the same time on the same connection you should not have speed problems
try going to speedtest.net and test your speed and compare to ppl that have the same isp that are in your area. if alot of other ppl are having speed problems
switch to comcast !!!! lol

Not like that sharing will not makes the internet slow,But if all download or watching online Videos means sure the internet speed will get slow,You can use the latest browsers in all Systems,Use the Good Router ,Install firewall protection and reset the Modem twice daily it will helps to make the internet speedy always,You can check the speed of the internet at here Ip-details.com
