We analyzed page load time and found that the first response time was 1.8 sec and then it took 13.1 sec to load all DOM resources and completely render a web page. This is a poor result, as 90% of websites can load faster.

Page optimization

  • HTML 297.5 kB
    Images 4.4 MB
    Javascripts 873.6 kB
    CSS 292.0 kB

    In fact, the total size of main page is 5.8 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. 70% of websites need less resources to load. Images take 4.4 MB which makes up the majority of the site volume.

    • Original 297.5 kB
    • After minification 255.6 kB
    • After compression 33.5 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. This page needs HTML code to be minified as it can gain 41.8 kB, which is 14% 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 264.0 kB or 89% of the original size.

    • Original 4.4 MB
    • After optimization 3.8 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. Obviously, Nrj needs image optimization as it can save up to 526.5 kB or 12% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.

    • Original 873.6 kB
    • After minification 832.0 kB
    • After compression 264.7 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 608.9 kB or 70% of the original size.

    • Original 292.0 kB
    • After minification 235.0 kB
    • After compression 36.6 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. needs all CSS files to be minified and compressed as it can save up to 255.4 kB or 87% of the original size.

Our browser made a total of 135 requests to load all elements on the main page. We found that 67% of them (90 requests) were addressed to the original, 16% (22 requests) were made to and 7% (9 requests) were made to The less responsive or slowest element that took the longest time to load (8.1 sec) belongs to the original domain

Additional info on


The browser has sent 124 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Nrj. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 26 to 1 for JavaScripts and from 27 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 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

Normal result


JA ja 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 Japanese 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 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

The server of is located in Japan, but, unfortunately, we cannot identify the countries where the visitors come from and thus it’s impossible to define if the distance can potentially affect the page load time.

Good result

Poor result

Social Sharing Optimization

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