How many executors can I have for a Jenkins Windows build node?
You can specify the executors of your node in his configuration.
Manage Jenkins -&gt; Manage Nodes -&gt; Configure Node -&gt; Number of build processors
In environments where we only run scripts etc. we have one executor per core.
But if you have large build jobs and the performance is important for you, you should read this article from the jenkins documentation.
