I've started collecting resources on Drupal performance in a "Big / Badass List"-style Github repo:
https://github.com/charginghawk/drupal-performance-resources
Mainly it addresses the lack of a performance factoid on the #drupal IRC channel. If anybody has any suggestions for good articles or blogs on Drupal performance, please let me know, or even make a pull request!
Also, I'd love to filter the Drupal Planet feed to posts on the topic of performance - if anybody has ideas on how to do this, please let me know.

Performance Tuning Checklist

made a dropbucket after doing some research into additional opcache tuning. Granted this only applies to PHP 5.5+ (apcu part only to 5.5 unless you compile manually.. which I don't).

APC, Varnish, Memcache, and Caching Beyond Drupal Core
Here's a blog post I wrote two years ago outlining a basic setup of APC, Memcache, and Varnish to improve performance on Drupal 7.x sites:
