2.2 MB
702.5 kB
In fact, the total size of Opencvlibrary.sourceforge.net main page is 2.2 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. 65% of websites need less resources to load. Javascripts take 899.9 kB which makes up the majority of the site volume.
Potential reduce by 333.0 kB
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 333.0 kB or 75% of the original size.
Potential reduce by 26.4 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. Obviously, OpenCV Library Source Forge needs image optimization as it can save up to 26.4 kB or 14% of the original volume. The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.
Potential reduce by 585.8 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. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 585.8 kB or 65% of the original size.
Potential reduce by 542.4 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. Opencvlibrary.sourceforge.net needs all CSS files to be minified and compressed as it can save up to 542.4 kB or 83% of the original size.
Number of requests can be reduced by 69 (58%)
