Good article covering the basics of page speed optimization



nice. I always try to keep my pages as lean and mean as possible.

One thing I didn't see mentioned in the article is to always code your <img> tags with a height and/or width attribute. Makes a huge difference in a page not loading like shit (images flickering and jumping around in a split second).

Also, another good site I found recently is TinyPNG ...it works really well

I hate seeing web designs (talking to you, WooThemes) that has like 40 HTTP requests per page.
 
Mentioned in the comments, but CDNs FTW!

This is more UX than page-size-opt, but all my photographer/artist/jewelry/landscape clients that require nice imagery for their businesses have a Flickr pro account that pulls high-res images from Flickr. Bonus on server load/hosting costs to them, and bonus to their users for faster downloads.
