Title: |
Load Testing - issues that can arise when think time is reduced or eliminated. |
|
Topic: |
Simulation of peak / worst-case loads during Load-Testing may involve shortening the periods in the simulated interactions that represent client processing time and operator response time. This allows the interaction to be completed more quickly thus allowing a load generator to perform more interactions per second. The premise for this approach is that shortening these external delays does not alter the demands that each interaction places on the system. Whilst this is true for the direct processing required to deliver the interaction thare are secondary effects that arise from shortening the duration of each interaction. These secondary effects create a risk that Load-Testing may not be representative and will fail to detect problems. This paper discusses some of these issues. |
