We analyzed page load time and found that the first response time was 768 ms and then it took 10.1 sec to load all DOM resources and completely render a web page. This is a poor result, as 85% of websites can load faster.

Page optimization

  • HTML 60.3 kB
    Images 1.4 MB
    Javascripts 95.6 kB
    CSS 61.7 kB

    In fact, the total size of main page is 1.6 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. Images take 1.4 MB which makes up the majority of the site volume.

    • Original 60.3 kB
    • After minification 58.7 kB
    • After compression 14.4 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 45.9 kB or 76% of the original size.

    • Original 1.4 MB
    • After optimization 1.4 MB

    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. Apc images are well optimized though.

    • Original 95.6 kB
    • After minification 73.0 kB
    • After compression 26.7 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 68.9 kB or 72% of the original size.

    • Original 61.7 kB
    • After minification 54.8 kB
    • After compression 9.2 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 52.5 kB or 85% of the original size.

Our browser made a total of 69 requests to load all elements on the main page. We found that 17% of them (12 requests) were addressed to the original, 57% (39 requests) were made to and 4% (3 requests) were made to The less responsive or slowest element that took the longest time to load (4.4 sec) relates to the external source

Additional info on


The browser has sent 63 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Apc. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 13 to 1 for JavaScripts and as a result speed up the page load time.











Possible request optimization













Normal result


As for redirects, our browser reached this domain in two steps. The first redirect led to, then it was forwarded to, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

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 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 iso-8859-1. 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.

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:
