"Compressing the following resources with gzip could reduce their transfer size by 2MiB (85% reduction)." The irony is that the page headers say mod_deflate is installed, so they literally need just to add the line to say "compress html" (and JS, and CSS) to reduce the FAQ page download from 2.2MB to a 0.3MB (assuming there want to leave the commenting as it is). Experience suggests they probably want to do this, the line is something like: AddOutputFilterByType DEFLATE text/html Can be in that hosts config, add extra MIME types (CSS, JS) as required. There is probably a Wordpress plugin to do this for you by now. I don't think I've seen a Google Page Speed score so low 15/100 and they are using Wordpress, my own blog on Wordpress scores 90/100 and I didn't do anything specific that I hadn't done for previous websites (i.e. enable compression). https://developers.google.com/pagespeed/ I can't immediately see why it is so slow on Firefox, it isn't the Javascript, but Page Speed is mopping about a lot of redirects to gravatar.com. My guess would be that Gravatar.com requests are handled slightly more efficiently in Chrome. Also I've never seen a web page exceed the Firebug Log Limit before (more than 500 requests in one page, almost all to 0.gravatar.com, which is a bad idea as browsers limit the number of connections to one server to 6). Gravatar.com also uses a low cache time, so the browser will recheck those 100's of requests every 5 minutes (sigh). I think this commenting system just doesn't scale to this number of comments with Avatars. Anyway this article says Wordpress has a disable Avatar feature for the commenting which will remove the hundreds of image fetches required to load the FAQs page. Probably wise to do this if they want to avoid Google penalties for page load times. Of course the cool thing to do would be to load the Avatars after the page has loaded, or even as the user scrolls to the relevant comments, but if Gravatar haven't done this yet they would lose the earlier comments (which is not cool). http://www.seomofo.com/wordpress/comments-slow-page-speed.html -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
