We are hosting our web application http://timr.com on a server located in Germany. The server handles a high load of traffic very well and everything works as desired in terms of performance and load times.
However we sometimes get complaints from our overseas users (US, South America) that the experience slow page loading times.
What would be the best way to test the performance of a web application "as if you are on another continent"? I want to make sure that the distance between the server and the user is no problem?
