Page optimization

  • HTML 49.9 kB
    Images 188.3 kB
    Javascripts 26.3 kB
    CSS 0 B

    In fact, the total size of main page is 264.5 kB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 30% of websites need less resources to load. Images take 188.3 kB which makes up the majority of the site volume.

    • Original 49.9 kB
    • After minification 36.4 kB
    • After compression 8.4 kB

    HTML optimization

    HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. This page needs HTML code to be minified as it can gain 13.5 kB, which is 27% of the original size. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 41.6 kB or 83% of the original size.

    • Original 188.3 kB
    • After optimization 170.7 kB

    Image optimization

    Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Tcs Home images are well optimized though.

    • Original 26.3 kB
    • After minification 26.3 kB
    • After compression 10.9 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 15.4 kB or 58% of the original size.

Our browser made a total of 34 requests to load all elements on the main page. We found that 94% of them (32 requests) were addressed to the original, 6% (2 requests) were made to The less responsive or slowest element that took the longest time to load (798 ms) belongs to the original domain

Additional info on


The browser has sent 33 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Tcs Home. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 5 to 1 for JavaScripts and from 10 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 1 other domain. 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

Good result


VI vi language flag


VI vi 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 it matches the claimed language. 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.

Poor result

Visitor World Map

Country of origin for 100% of all visits is Vietnam. It lies approximately 5990 miles away from the server location (France) 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.

Poor result

Poor result

Social Sharing Optimization

Open Graph description is not detected on the main page of Tcs Home. 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:
