Web Performance Statistic of the Week 1/11
- Tags:
Google found that an extra 500 ms in latency cost them 20% of their search traffic - 5 YEARS AGO!!
At the Web 2.0 conference in 2006, Google VP Marissa Mayer made a presentation where she shared the above statistic. The negative affect of incremental degrading response time was uncovered because of differences in the number of search results that people wanted. An experiment with a segmented group of searchers had 30 results instead of the normal 10. The page with 10 results took 400 ms to generate, while the page with 30 results took 900 ms. This experimental, scientifically segmented group had 20% less traffic; thus the revenue to Google also dropped by 20%.
I don't know how we perceive a half of a second delay, but it obviously makes a difference.
