Plug for my (open source) project, mod_pagespeed: it can automate all of these. > not using image sprites sprite_images filter: https://developers.google.com/speed/pagespeed/module/filter-image-sprite https://developers.google.com/speed/pagespeed/module/filter-... > not using a cookieless domain for images and other static content MapRewriteDomain directive: https://developers.google.com/speed/pagespeed/module/domains#mapping_rewrite https://developers.google.com/speed/pagespeed/module/domains... > not using a CDN Once you have a (pull) CDN set up, mod_pagespeed can rewrite your resources onto it with the same MapRewriteDomain directive. > blocking javascript - worse if it’s in the head defer_javascript filter: https://developers.google.com/speed/pagespeed/module/filter-js-defer https://developers.google.com/speed/pagespeed/module/filter-... > not minifying your javascript and CSS rewrite_javascript: https://developers.google.com/speed/pagespeed/module/filter-js-minify https://developers.google.com/speed/pagespeed/module/filter-... rewrite_css: https://developers.google.com/speed/pagespeed/module/filter-css-rewrite https://developers.google.com/speed/pagespeed/module/filter-... > not optimizing caching policies mod_pagespeed automatically longcaches everything: https://developers.google.com/speed/pagespeed/module/filter-cache-extend https://developers.google.com/speed/pagespeed/module/filter-... > not gzipping your content - most if not all popular web servers support some type of compression mod_pagespeed automatically enables gzip compression About half of these are enabled by default (minifying css and js, optimizing caching, turning on gzip) and the rest need to be configured. (If I were making the list I would also have included resource combining for css and js, which mod_pagespeed does by default.)
