Theo 05 December 2012 Great post! There are very much articles about responsive webdesign but only few handle performance. As i redesigned my site i was looking for possibilities to test the loading time on mobile and i came across weblenz, it’s available in the app store. The lite version is free and tests time, items and the size of a website. I like it because i do not have to simulate latency, i can test in the “real world” on my iphone. Thank you!
