Performance diagnostics is not about collecting more data. It's about asking better questions.
Many Firebird performance investigations begin the same way: execution plans are reviewed, configuration is checked, system resources are monitored, and yet the real cause remains elusive. Every observation appears correct, but none explains the behavior of the system as a whole.
This book introduces a different approach.
Rather than presenting another collection of tuning tips or optimization recipes, it develops a structured framework for diagnosing Firebird performance problems. It shows how to move systematically from observed symptoms to defensible explanations by classifying problems, selecting appropriate investigation strategies, interpreting evidence correctly, and choosing diagnostic tools with intent.
Designed for experienced Firebird developers, administrators and support engineers, the book focuses on the reasoning process behind successful diagnostics rather than individual techniques.
