Performance Testing Principles and Practices Cube - Print me off and stick me together!!! A simple visual way of representing some heuristics to get you thinking about what to do when performance testing.

To enable us to show a
change in performance
we need our
benchmarks to be
repeatable
Only changing one thing at a
time when testing means
you know what caused
the effect you witnessed

Establish a transaction
volume model and seek
to emulate it to make
everything involved as
realistic as possible
Consider the impact of
your change on other
systems
Understand the impact.
Investigate & monitor the
environment and the
application
Transaction volume model (TVM)
