Jenkins poll vs webhook

Question

I am new to Jenkins, was curious to know how does the Jenkins poll feature works and how does it utlize system resources.

What could be best practice to use in CI system - Jenkins poll or github webhook and why?

Answer 1

This is a very easy answer, answered by Kohsuke, the creator of jenkins himself. Polling is less efficient, both for your computers, and for your people, since you have to wait--on the order of minutes--for your builds to happen, instead of them happening essentially instantly. We used to use polling before we switched to jenkins, and the biggest thing that people talk about is that "holy crap, jenkins builds fast." It's not jenkins, it's webhook pushing to trigger builds. Do that.
