Sometimes in our lives, we all have pain, we all have sorrow. And sometimes we also have to launch Drupal sites into the wild blue yonder. It's during these times that we separate the grown-ups from the n00bs, and we see how well our site performs under heavy load. Many of us didn't need to worry about speed, page size, and server load in our younger years when we were building sites for Uncle Don and Aunt Sue, but eventually you get that big client, and you need some help.
