To start, we'll address the Runbook Server Throttling. By default, a Runbook server can run a maximum of 50 Runbooks in parallel, and this number can be changed to better suit your environment requirements or even take full advantage of your servers. You'll see yourself tweaking this to accommodate more or less demanding Runbooks in your system, and due to the impact on the system itself, you might feel the need to increase or decrease the number of parallel Runbooks allowed to be executed.
To do so, you'll need to use the Runbook Server Throttling tool. Navigate to
C:\Program Files (x86)\Microsoft System Center 2012 R2\Orchestrator\Management Server and execute a command prompt from there, and in it, the following command (per example: aspt packtscorchrb 70):
aspt <RunbookServer> <MaxRunningRunbooks>
