Advices

  • HTML files can be minified.
    You should apply some of the minify techniques, also file size can be sufficiently (up to 80%) reduced via gzip.
  • CSS files are loaded via conditional comments.
    Detected some CSS files (total 1) that are loaded via conditional comments. You should combine all files into one and hide special IE styles with star hacks (i.e. * html) or may be include them into HTML. It allows you to reduce the number of requests to the server.
  • CSS files can be minified.
    You should use this tool to compress CSS files (based on CSS Tidy). After this you can output CSS files gzipped from the server (total benefit up to 85%).
  • 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: 51.
  • 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%).
  • 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.
  • 404-errors detected (Page Not Found).
    Broken links to resources detected (total 1). Every such link wastes time while web page loading so all of them should be removed or replaced with the right ones.
  • Some of GIF images can be reduced in size.
    Detected GIF images that can be minified (total: 12) if converted to PNG (i.e. with gif2png tool). More about PNG benefits.
  • Some PNG images can be minified.
    Detected PNG images (total: 14) that can be minified (i.e. with pngcrush tool). More about PNG benefits.
  • Some of JPEG images can be minified.
    Detected JPEG images (total: 8) that can be lossless minified (i.e. with jpegtran tool or Windows-ported jpeg package that includes jpegtran utility).

Remarks

  • Inline event handlers detected.
    Detected event haldres size in HTML attributes onclick, onmouseover etc equals to 2986 (14%). 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 quite 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.
