Compare the speed and resource compatibility of a web page delivered from US vs. China
About the China Code Test
Websites not built with an audience in China in mind load an average of 5-8x slower. This is the combined result of a site’s hosting infrastructure, code-level compatibility with China’s internet (e.g. blocked resources), the optimisation, or lack thereof, of its resources, and China networks. This test scans up to 10 pages of your site looking at the HTML, CSS, and JavaScript to identify incompatible resources that could cause your page to load slowly, or incompletely in China.
