Key Findings

We analyzed Rhino3d.us page load time and found that the first response time was 5.5 sec and then it took 51.4 sec to load all DOM resources and completely render a web page. This is an excellent result, as only a small number of websites can load faster. Unfortunately, there were 5 request timeouts, which can generally increase the web page load time, as the browser stays idle while waiting for website response.

Our service has detected that Chinese is used on the page, and it matches the claimed language. Our system also found out that Rhino3d.us main page’s claimed encoding is gbk. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.
