We analyzed Scipy-lectures.org page load time and found that the first response time was 21 ms and then it took 579 ms to load all DOM resources and completely render a web page. This is an excellent result, as only 5% of websites can load faster.

Page optimization

  • HTML 107.7 kB
    Images 441 B
    Javascripts 0 B
    CSS 49.2 kB

    In fact, the total size of Scipy-lectures.org main page is 157.4 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. 35% of websites need less resources to load. HTML takes 107.7 kB which makes up the majority of the site volume.

    • Original 107.7 kB
    • After minification 107.0 kB
    • After compression 17.4 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 90.3 kB or 84% of the original size.

    • Original 441 B
    • After optimization 371 B

    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, Scipy Lecture S needs image optimization as it can save up to 70 B or 16% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

    • Original 49.2 kB
    • After minification 34.2 kB
    • After compression 8.6 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. Scipy-lectures.org needs all CSS files to be minified and compressed as it can save up to 40.6 kB or 82% of the original size.

Visitor World Map

Country of origin for 29.4% of all visits is India. It lies approximately 4380 miles away from the server location (Netherlands) 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 Scipy-lectures.org page load time for the majority of users is moving the server to India or just closer to the user base.

Social Sharing Optimization

Open Graph description is not detected on the main page of Scipy Lecture S. 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:
