I've been thinking quite a lot about a website's response time in general. I have read somewhere; if the website doesn't load within 3 seconds, then the visitor will closed the page. So if I have a US based website with streaming videos and want to target people in Europe; I have to expect many of my visitors will close down the site even before the video starts. So If I want to target international (people from US, Europe, Asia etc.) I have to have a server in either every country or on every continent. But let's say I want to target countries in South America, how will the response time be when I have a US based website? Will I loose visitors because of the response time? Or will the response time be low?
