Some of the key "take-aways" from TechEd 2010 North America:

• Caching is key to performance, consider your caching strategy very carefully.
• Disable viewstate if possible.

• Consider CDN's or subdomains for graphics and other static content.
• Place javascript at the bottom of the page, CSS at the top.
• Consider CSS sprites for icons and other "small" graphics.
