Advices

• Automated website acceleration
  Install WEBO Site SpeedUp to your website amazon.com. It allows you to significantly increase its load speed and save up to 98% of its traffic.
• HTML files can be minified.
  HTML files are already gzipped but in addition you can apply some of the minify techniques or (and) increase gzip level on server side. Optimal gzip level can be calculated with the following tool.
• More than 1 CSS file is loaded.
  You should combine all files into one or may be even include them into HTML. It allows you to reduce the number of requests to the server.
• CSS files can be minified.
  CSS files are already gzipped but additionally you can use this tool to compress CSS files (based on CSS Tidy).
• CSS files are too large.
  You should reduce their size by exclusion unnecessary styles, minimization pathes to background images, re-group selectors, or review current classes/IDs naming logic.
• Caching is disabled for static files.
  You should output all statis resources (images, CSS, JS and multimedia files) with caching headers (Cache-Control) to reduce number of requests to the server from browser when user visits your website in the second time or open different pages. How to enable caching for your website. Total non-cached files: 1.
• Detected more than 1 JavaScript file.
  Yuo should combine all files into one or include them all into HTML. This will reduce number of requests to the server. Also you can use unobtrusive Javacript techniques to load your JavaScript files.
• JavaScript files can be minified.
  You should use Packer from Dean Edwards or YUI Compressor (comparison of JavaScript minimization tools). After this you can gzip your JavaScript files (total benefit up to 85%).
• JS files are too large.
  May be you should separate this to several parts and load only necessary resources. Also unobtrusive Javascript techniques can help.
• Duplicates are detected.
  CSS and JavaScript duplicates must be removed. Multiple uses of the same images can be avoided with CSS rules and background images.
• Redirects detected.
  Every redirect increases current resource load time, so it should be removed. Total detected redirects: 1.
• Some of GIF images can be reduced in size.
  Detected GIF images that can be minified (total: 15) if converted to PNG (i.e. with gif2png tool). More about PNG benefits.
• Some PNG images can be minified.
  Detected PNG images (total: 20) that can be minified (i.e. with pngcrush tool). More about PNG benefits.

Remarks

• Inline event handlers detected.
  Detected event haldres size in HTML attributes onclick, onmouseover etc equals to 223 (1%). If all of event handlers are moved to an external file then global cacheability of all the website will increase and content will be separated from behaviour. May be unobtrusive JavaScript and this combined window.onload handler can help.
• More than 1 CSS image is loaded.
  You should combine CSS images with the CSS sprites technique (and the following tool). So you will reduce numebr of requests to the server.
• CSS images size is very large.
  Perhaps it can be reduced if you use another graphic format or inlcude only necessary CSS rules.
• More than 1 image is loaded.
  Perhaps it's possible to decrease their quantity by Image Map technique.
• Images size is very large.
  Perhaps it's possible to decrease their size if you use another graphic format or include only necessary images on the page.
• 1-pixel GIF (spacers) detected.
  There are some 1-pixel GIF (size 43 bytes) in website files (total 1)) detected. There is every likelihood that they are improperly used for some decorative effects (elemens borders substitutions or background holders). Now browsers support all kind of CSS tricks very well so you don't need to use any of table-layout methods and can clean up your HTML code from such outdated hacks. This will reduce number of requests to the server and make you HTML code more semantic and less in size (about 30% with moving to div from table).
