Key Findings

We analyzed Tdk.com page load time and found that the first response time was 378 ms and then it took 59.6 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 24 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.
