The document discusses the flawed approach of "racing performance" without proper preparation. It argues that jumping straight into performance testing without checking components like tires, fuel levels, and ensuring the system is functioning properly leads to "fatal consequences" like crashes. Some reasons this approach still occurs include a lack of performance culture, confusion between performance and load testing, and viewing all problems as requiring load automation. The document promotes better approaches like verifying components, defining standards, stress testing parts individually and together before integration, using meters to monitor system functions, conducting lab tests, and test driving the system before attempting high-stakes races.

Who am I?
• I am Leandro Melendez
• Performance tester, scripter, engineer and idealist. Perf Manager @QualiTest
• Lot’sa experience on several performance projects for 10 years.
• Found lots of vices, weird paths of action and plain ignorance.
• Decided to get a secret identity and wear the spandex moustache to fight against
bad practices, process inertia and plain ignorance as Señor Performo.
• All this through a blog (www.srperf.com), Social NW’s (@srperf), hosting the
Spanish version of the performance testing podcast PerfBytes en Español.
• Last, but not least, through public speaking, spreading the word of performance,
which we will do here today.
