This is the result of pagespeed modifications applied to the arkusnexus website.
Adding half a second to a search results page can decrease traffic and ad revenues by 20 percent, according to a Google study. The same article reports Amazon found that every additional 100 milliseconds of load time decreased sales by 1 percent. Users expect pages to load in two seconds, and after three seconds, up to 40 percent will simply leave.
This data set allowed me to view the following data points:
- If your site loads in 5 seconds it is faster than approximately 25% of the web
- If your site loads in 2.9 seconds it is faster than approximately 50% of the web
- If your site loads in 1.7 seconds it is faster than approximately 75% of the web
- If your site loads in 0.8 seconds it is faster than approximately 94% of the web
