When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times. This is because Virtual User 1 is the monitor Virtual User but this Virtual User does not run in the replica meaning it ends immediately. Step Workloads.

The queues component of our methodology comes from Performance Monitor counters, which provide a view of system performance from a resource standpoint.". Tom Davidson, Opening Microsoft's Performance-Tuning Toolbox SQL Server Pro Magazine, December 2003.

When a system ‘scales’ it is able to deliver higher levels of performance proportional to the system resources available to it. In particular, this means as we add CPU cores and increase the system load, we see higher performance. In this example, we will compare MySQL 5.7.33 and MySQL 8.0.25 and MySQL 5.7.33.

It is of note that we have not discussed the operating system yet, that is because the source code and the code included with the pre-packaged versions is identical whether it is running on Linux or Windows on x86-64 architecture (or any other platform).
