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 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%).
  • 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: 6.
  • 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.
  • Too many hosts.
    Website resources are located on a lot of different hosts. This can sufficiently slow down website due to numerous DNS lookups and connection outlay. You should use not more than 4 hosts. Hosts number detected: 7
  • 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: 1) if converted to PNG (i.e. with gif2png tool). More about PNG benefits.
  • Some PNG images can be minified.
    Detected PNG images (total: 2) that can be minified (i.e. with pngcrush tool). More about PNG benefits.

Remarks

  • 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 quite large.
    Perhaps it's possible to decrease their size if you use another graphic format or include only necessary images on the page.
  • Detected more than 1 JavaScript counter.
    There are several (total 3) 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.
