We analyzed page load time and found that the first response time was 91 ms and then it took 854 ms to load all DOM resources and completely render a web page. This is quite a good result, as only 10% of websites can load faster.

Page optimization

  • HTML 64.4 kB
    Images 976.8 kB
    Javascripts 1.1 MB
    CSS 220.0 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. 50% of websites need less resources to load. Javascripts take 1.1 MB which makes up the majority of the site volume.

    • Original 64.4 kB
    • After minification 56.6 kB
    • After compression 12.3 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 7.8 kB, which is 12% 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 52.1 kB or 81% of the original size.

    • Original 976.8 kB
    • After optimization 896.8 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. SOLIDWORKS images are well optimized though.

    • Original 1.1 MB
    • After minification 1.0 MB
    • After compression 300.1 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 797.0 kB or 73% of the original size.

    • Original 220.0 kB
    • After minification 163.4 kB
    • After compression 31.0 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. needs all CSS files to be minified and compressed as it can save up to 188.9 kB or 86% of the original size.

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 13 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 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 English 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.

Normal result

Visitor World Map

Country of origin for 100% of all visits is India. It lies approximately 8260 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 India or just closer to the user base.
