Using resource groups : Configuring a resource group : Allocating Factories for a resource group
 
Allocating Factories for a resource group
Valid values for Max factory property range from 1 to twice the number of processors on your machine. When setting this property, consider the Factories allocated for other resource groups. Also, consider using FactoryIdleTimeout to make unused Factories available. Increasing the number of Factories impacts performance. Setting the value to 0 disables the resource group for the server. By default, iHub allocates one Factory process to each default resource group during installation.
