Key Findings

We analyzed Adsun.vn page load time and found that the first response time was 1.6 sec and then it took 64.8 sec to load all DOM resources and completely render a web page. This is a poor result, as 95% of websites can load faster. Unfortunately, there were 36 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.
