Unfortunately, there was 1 request timeout, which can generally increase the web page load time, as the browser stays idle while waiting for website response.

Page optimization

  • HTML 101.3 kB
    Images 1.5 MB
    Javascripts 514.7 kB
    CSS 288.0 kB

    In fact, the total size of main page is 2.4 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 65% of websites need less resources to load. Images take 1.5 MB which makes up the majority of the site volume.

    • Original 101.3 kB
    • After minification 79.4 kB
    • After compression 18.1 kB

    • After compression 135.7 kB

    JavaScript optimization

    It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 379.0 kB or 74% of the original size.

    • Original 288.0 kB
    • After minification 275.8 kB

Our browser made a total of 125 requests to load all elements on the main page. We found that 57% of them (71 requests) were addressed to the original, 15% (19 requests) were made to and 6% (8 requests) were made to The less responsive or slowest element that took the longest time to load (20.3 sec) belongs to the original domain

Additional info on


The browser has sent 118 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Dothi. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 22 to 1 for JavaScripts and from 8 to 1 for CSS and as a result speed up the page load time.











Possible request optimization













Normal result

IP address uses IP address which is currently shared with 4 other domains. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.

Language and encoding

Normal result


VI vi language flag


N/A  language flag





Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise can be misinterpreted by Google and other search engines. Our service has detected that Vietnamese 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 main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.

HTTPS certificate

SSL Certificate has no SSL certificate. Web browsing can be safer with HTTPS connection, so we suggest that it should be obtained for this site.

Normal result

Visitor World Map

Country of origin for 100% of all visits is Vietnam. It lies approximately 8420 miles away from the server location (United States) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up page load time for the majority of users is moving the server to Vietnam or just closer to the user base.

Social Sharing Optimization

Open Graph description is not detected on the main page of Dothi. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
