Advices

• 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.
• 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).
• 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: 7.
• ETag or Last-Modified are disabled for some files.
  ETag (or Last-Modified) are already enabled for website but are disabled for some external resources. You should enable for all static files ETag or Last-Modified headers (and reduce thereby number of subsequent requests to the server). May be it is possible to host external files on the website and increase its total cacheability. How to enable ETag for Apache.
• 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.
• Redirects detected.
  Every redirect increases current resource load time, so it should be removed. Total detected redirects: 2.
• Some of GIF images can be reduced in size.
  Detected GIF images that can be minified (total: 6) if converted to PNG (i.e. with gif2png tool). More about PNG benefits.
• Some PNG images can be minified.
  Detected PNG images (total: 1) 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 13 (0%). 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.
• Detected more than 1 JavaScript counter.
  There are several (total 2) counters on the website that are inserted with JavaScript. Large amount of them can sufficiently slow down website. May be some of them can be removed.
