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 are loaded via conditional comments.
    Detected some CSS files (total 3) 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.
    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: 4.
  • ETag or Last-Modified headers are disabled.
    Some of the files of the website already have ETag / Last-Modified headers (total: 32). You should enable cache headers ETag or Last-Modified for all static files (to reduce number of subsequent requests to the website from end-user browser). How to enable ETag for Apache. Total files without ETag / Last-Modified: 2.
  • 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.
  • 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.
  • 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: 5
  • 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: 8) 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.
  • Some of JPEG images can be minified.
    Detected JPEG images (total: 1) 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 66 (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.
  • More than 1 image is loaded.
    Perhaps it's possible to decrease their quantity by Image Map technique.
