The replicas are defined in steps.xml in the config directory to determine how many virtual users each replica will configure, how soon after the previous instance has started the replica should start and how long it will run for. <steps> Note that it is expected for Virtual User 1 of the replicas to end immediately with the message.

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.

That was the provocative thesis of a much-talked-about article from 2003 in the Harvard Business Review by the US publicist Nicolas Carr. The end effect is that the complexity of the system increases, which is not efficient. How companies can use ideas from mass production to create business with data. This pattern should be broken.
