The importance of speed can be easily verified by research conducted by Amazon and Google. Greg Linden during his time at Amazon presented findings that 1second of latency costs Amazon 1% in sales. Marissa Mayer (VP User Experience at Google) has presented research showing that a 0.5 second increase in page load times reduces repeat traffic by 20%. This leaves us with one simple conclusion: A faster website equals more sales. - Mark Rochefort
