Key Findings

We analyzed Ocd.vn page load time and found that the first response time was 658 ms and then it took 46.6 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 19 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.
