Most of these were suggested to me by YSlow and Matt Mullenweg at Wordcamp.

  • Installed wp-cache
  • Enabled mod_deflate for gzip compressed html, javascript, and css
  • Disabled ETags
  • Added Expires headers
  • Moved CSS to the top of the <head> container
  • Removed the AJAX calendar wordpress plugin (this was hammering the database)

The front page now renders in about 1.5 seconds instead of the 4 seconds that it used to take. The next step is to remove all of the little mini icons in the sidebar and replace them with sprites which will reduce the number of HTTP requests from 21 down to 10. Running JSMin on my Javascript probably wouldn’t hurt either.

UPDATE: Apparently, you should only disable ETags if you’re running a server farm. Doing so for a single server installation probably does more harm than good.
