SXSW - Even Faster Websites

Steve Souders, writer of YSlow, gave a talk about making websites even faster.  Here's my notes:

• parallel script loading
  
• if you use script dom element method, make sure you check race conditions in IE
  
• DO NOT put inline scripts after stylesheets
  
• iframe suck

UPDATE:

One this that's interesting to note about this PowerPoint deck are slides 66 & 67.  They show how the frontend optimization discussed impacts a business's bottom line.  This is how you would sell in the extra initial cost.
