Meaningful Performance Test

Non-linear:
Analogy-10 women cannot work together to get a baby in a month

Problem resolution:

Need profiling logs when the test is run with
Correct application and version
Usecase
Config
Database
Problematic issue must be reproduced

Scale is important
Water in a bucket and beach and their physics are different

Performance issues
-Performance Tips are for waiters, analysis for engineers
-Technicians read from the list and they become engineers when they add to the list

All CPU's WAIT at the same speed

Maserati has to wait in a STOP sign like a single threaded application, CPU works on the running code,not the waiting code!

Data quantity and quality plays a major role in test validity
