So we have created some scripts that will show us our possibly concurrency, but what does this mean and how do we work out how many session engines we will need. This article will explain, what a session engine is and why we need at least one of them. We will show you some test results that we have run with the Data Collection Load tool and some standard scripts.

How many concurrents : Part 4

In the previous articles we designed some scripts to read the IVW log files to work out what the concurrency was, next we will write a script that will try and Estimate what sort of concurrency certain survey criteria might produce.
