   ӨڹΛ༩͑Δྫ Our experiments demonstrate that slowing down the search results page by 100 to 400 milliseconds has a measurable impact on the number of searches per user of -0.2% to -0.6% 
 (averaged over four or six weeks depending on the experiment).
 That's 0.2% to 0.6% fewer searches for changes under half a second! Speed Matters - Google AI Blog ref. https://ai.googleblog.com/2009/06/speed-matters.html
6. ©2018 Wantedly, Inc. The result of rebuilding our pages for performance led to a 40 percent decrease in Pinner wait time, a 15 percent increase in SEO traffic
 and a 15 percent increase in conversion rate to signup. Driving user growth with performance improvements - Pinterest Engineering Blog ref. https://medium.com/@Pinterest_Engineering/driving-user-growth-with-performance-improvements-cfc50dafadd7 ΞϓϦέʔγϣϯͷύϑΥʔϚϯε͕
