What is Performance Modelling?

Performance modelling is the process of simulating various user and system loads against varying system configurations by using a mathematical approximation of how the model works.  Generally this does not require the use of a Load Test environment.  This is typically much cheaper than performance testing and can produce very accurate results.


For example, servers are monitored while low level user transactions are executed against the system.  A typical Performance Modelling process results in:

  1. The server counters are correlated with transaction response times.
  2. The information along with system specifications are fed into a mathematical modelling tool.
  3. After the data has been entered various models are produced to demonstrate the system's behaviour in varying configurations and user and/or system loads.
  4. The outputs of performance modelling are used for capacity planning.
