Scalability and Estimation

May 28, 201439 min
You journey through a land of both shadow and substance and you can see the curve on the CPU graph is totally going in the wrong direction - a little worse every minute, every user and soon enough the system will just tip completely over. But how can you test for those conditions beyond the capacity of your test lab environment? You gotta estimate future performance based on the results you gather in the lab. Extrapolation might be evil, but not understanding basic scalability concepts is essential to your success in performance testing and engineering.
