As Drupal continues to experience huge growth with government and enterprise clients, the scale and complexity of Drupal implementations also grows. A common issue affecting these bigger projects is poor website performance. Problems of this nature have huge and costly impacts on the customer; lost sales and advertising revenue, loss of consumer confidence and brand legitimacy, SEO penalties, increased hosting infrastructure costs - the list goes on. Not to mention the developers tasked with fixing the problem! The stakes are high, the pressure is on, and the technical challenges are real - not a position many of us would choose to be in.
