In normal mode: total number of concurrent client connections to maintain. In swarm mode: number of clients to create in each batch.

Default value of this property is 10

Clients creation batch size

clientsCreationBatchSizeintegerOptional

In normal mode: number of clients to create in each initialization batch (to avoid overwhelming the server). In swarm mode: this parameter is ignored.

Default value of this property is 5
