Key Findings

We analyzed X-diver.net page load time and found that the first response time was 1.6 sec and then it took 104.1 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 9 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 Russian is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that X-diver.net main page’s claimed encoding is windows-1251. 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.
