Click here to check amazing Qt Project content for Iran. Otherwise, check out these important facts you probably never knew about qt-project.org

We analyzed Qt-project.org page load time and found that the first response time was 301 ms and then it took 2.2 sec to load all DOM resources and completely render a web page. This is quite a good result, as only 40% of websites can load faster.

Page optimization

  • HTML 41.6 kB
    Images 1.1 MB
    Javascripts 1.1 MB
    CSS 615.7 kB

    In fact, the total size of Qt-project.org main page is 2.9 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. 80% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Javascripts take 1.1 MB which makes up the majority of the site volume.

    • Original 41.6 kB
    • After minification 39.0 kB
    • After compression 9.4 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. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 32.2 kB or 77% of the original size.

    • Original 1.1 MB
    • After optimization 851.8 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. Obviously, Qt Project needs image optimization as it can save up to 249.6 kB or 23% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

    • Original 1.1 MB
    • After minification 1.1 MB
    • After compression 352.9 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 769.5 kB or 69% of the original size.

    • Original 615.7 kB
    • After minification 530.9 kB
    • After compression 87.1 kB

    CSS optimization

    CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Qt-project.org needs all CSS files to be minified and compressed as it can save up to 528.6 kB or 86% of the original size.

Requests

The browser has sent 55 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Qt Project. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 29 to 1 for JavaScripts and from 9 to 1 for CSS and as a result speed up the page load time.

IP address

Qt-project.org uses IP addresses which are currently shared with 15 other domains. The more sites share the same stack of IP addresses, 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.

Good result

Poor result

Visitor World Map

Country of origin for 29.9% of all visits is Iran. It lies approximately 3240 miles away from the server location (Ireland) 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 Qt-project.org page load time for the majority of users is moving the server to Iran or just closer to the user base.

Social Sharing Optimization

Open Graph description is not detected on the main page of Qt Project. 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:
