Key Findings

We analyzed Bbs.aliyun.com page load time and found that the first response time was 4.3 sec and then it took 40.4 sec to load all DOM resources and completely render a web page.

Unfortunately, there were 7 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.
