  2. Impact of the Performance is underrated • Every 100ms improvement in latency increases the revenue by 1% (2008)2008: 19,17 Bil €  191,7 Mil €2013: 74,51 Bil € … • 37-49% of users experiencing the performance problems leave the website or change to competition (2010) • Site impressions increase of 9% for every 400ms improvement in page loading time (2009) • 32% of all users leave the web pages that have loading times between 1-5 seconds (2010) • 1 (2) seconds delay reduces revenue by 3 (5) % (2010) • A user feels loading time 15% slower as it was in reality. He remembers it as being 35% slower. (2010)
