Page optimization

  • HTML 98.6 kB
    Images 235.1 kB
    Javascripts 748.0 kB
    CSS 325.3 kB

    In fact, the total size of main page is 1.4 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. Javascripts take 748.0 kB which makes up the majority of the site volume.

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 517.7 kB or 69% of the original size.

It lies approximately 3890 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 Spain or just closer to the user base.
