I am trying to run 20 processes in parallel. I changed the session as below, but having no luck. I am getting only up to 5 parallel processes per session.

$wo=New-PSWorkflowExecutionOption -MaxSessionsPerWorkflow 50 -MaxDisconnectedSessions 200 -MaxSessionsPerRemoteNode 50 -MaxActivityProcesses 50
Register-PSSessionConfiguration -Name ITWorkflows -SessionTypeOption $wo -Force
Get-PSSessionConfiguration ITWorkflows | Format-List -Property *

Is there a switch parameter to increase the number of processes?

This is what I am running:

Workflow MyWorkflow1
