We analyzed page load time and found that the first response time was 399 ms and then it took 3.7 sec to load all DOM resources and completely render a web page. This is a poor result, as 60% of websites can load faster.

Page optimization

  • HTML 214.3 kB
    Images 187.9 kB
    Javascripts 110.0 kB
    CSS 98.2 kB

    In fact, the total size of main page is 610.4 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. 50% of websites need less resources to load. HTML takes 214.3 kB which makes up the majority of the site volume.

    • Original 214.3 kB
    • After minification 211.0 kB
    • After compression 76.5 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 137.8 kB or 64% of the original size.

    • Original 187.9 kB
    • After optimization 174.7 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. Pcm images are well optimized though.

    • Original 110.0 kB
    • After minification 110.0 kB
    • After compression 39.8 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 70.2 kB or 64% of the original size.

    • Original 98.2 kB
    • After minification 76.9 kB
    • After compression 17.4 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 80.7 kB or 82% of the original size.

The browser has sent 50 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Pcm. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 19 to 1 for JavaScripts and from 8 to 1 for CSS and as a result speed up the page load time.

As for redirects, our browser was forwarded to before it reached this domain.

IP address uses IP address which is currently shared with 4 other domains. 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

Poor result


RU ru language flag


N/A  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 Russian is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that main page’s claimed encoding is windows-1251. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.

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 67.6% of all visits is Russia. It lies approximately 5610 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 Russia or just closer to the user base.

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