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 30.6 kB, which is 20% 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 125.9 kB or 83% of the original size.

After minification 957.0 kB

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. SPARK images are well optimized though.

JavaScript Optimization

-4%

Potential reduce by 888 B

Original 22.6 kB
After minification 22.6 kB
After compression 21.7 kB

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. This website has mostly compressed JavaScripts.

CSS Optimization

-16%

Potential reduce by 12.0 kB

Original 74.7 kB
After minification 74.7 kB
After compression 62.7 kB

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. Spark.ru needs all CSS files to be minified and compressed as it can save up to 12.0 kB or 16% of the original size.

Requests Now

After Optimization

The browser has sent 91 CSS, Javascripts, AJAX and image requests in order to completely render the main page of SPARK. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 16 to 1 for JavaScripts and from 4 to 1 for CSS and as a result speed up the page load time.

Accessibility Issues

These are opportunities to improve the legibility of your content.
