If you are a web developer or one of the people that actually care about your website(s) performance, and looking for ways to improve it, then Yahoo’s Best Practices for Speeding Up Your Web Site is definitely a must-read. If you are not, feel free to skip this post.
Yahoo has put up quite a research into this field and has compiled the 34 rules for your convenience. Separated into 7 categories : Content, Server, Cookie, CSS, Javascript, Images, and Mobile, some are just general stuff, such as: don’t scale your image, minify your javascript files, blah blah, but some are good to know, such as: implementing “Never expire” policy by setting a far future ‘Expires’ header, putting scripts at the bottom (never knew that it would make a difference), configuring ETags (wtf are ETags ?), and so on.
It’s been on the web for quite some time now, I wonder how I could missed this one. So, what are you waiting for ? Click the link. Go. Now. Scram! (be sure to come back here later though)
Oh, and, for you Firefox + Firebug users, there’s an add-on from Yahoo to scan for those points on any webpages and grade them accordingly, it’s called YSlow (lame name IMO, sorry Yahoo). Neat stuff. I mean, NEAT. I sure wish that I’ve known about this a long time ago. I’m bonking my head to the wall now, in deep regret. (don’t worry, I’ll survive)
