I've had to look at a few options for improving performance on this site. I noticed that the introduction of the Feedburner module and moving the RSS feeds [0] across to Feedburner had caused some performance issues.

As I write this, I'm making some changes to the site based on the Essential Steps to Speed up a Drupal Web Site [1] series of articles.

The current change is to implement the Block Cache Module [2], so you may see a couple of pieces of content duplicated while I switch from dynamic to cached content.
