Improving website performance is not the top of the list for bloggers – we tend to focus more on content. Yet today I came across a site that not only gives an analysis of your site performance but gives great info on why you need to fix the areas falling short and even does some of the work for you – just cut and paste fixes to css, html and htaccess files.
Definitely made an improvement to my site loading time on one of my blogs.
