Tuning Application Performance in Production
Even applications that have gone through rigorous testing in QA tend to have serious performance problems in production. Nearly every CIO or production manager has horror stories of applications that went live and failed. Yet with so much on the line, why are we in a constant firefighting mode? When confronted with new problems, we have to start with the basics and ask, "Is the problem in the application or in the infrastructure? How can I narrow it down fast?" Production tuning takes your good QA practices to the next level, and helps you get out of firefighting mode.
