Key Findings

We analyzed Itcn.cc page load time and found that the first response time was 4.6 sec and then it took 51.5 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 were 40 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.
