Key Findings

We analyzed Sdk.cn page load time and found that the first response time was 3.2 sec and then it took 34.2 sec to load all DOM resources and completely render a web page. This is an excellent result, as only a small number of websites can load faster. Unfortunately, there was 1 request timeout, which can generally increase the web page load time, as the browser stays idle while waiting for website response.
