The most popular and efficient tools for JPEG and PNG image optimization are Jpegoptim and PNG Crush.
Potential reduce by 227.7 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.

The browser has sent 50 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Wolfram. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 9 to 1 for JavaScripts and from 4 to 1 for CSS and as a result speed up the page load time.
