For a single Application Pool, how many Worker Processes should be allowed to run?

Honestly I don't know the effect of increasing or decreasing the number of worker processes.

I follow, and I'm looking to find it in the documentation, that you should not run more worker processes then twice the number of processor cores.

• In a single core system : 2
• In a dual core system : 4
• etc.

You should also be aware that increasing the worker processes creates a web garden. All worker processes have their own copy of application state, in-process session state, caches, and static data.
