Key Findings

We analyzed Nba.co page load time and found that the first response time was 192 ms and then it took 23 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.
