Is there a maximum number of cores Ignition will use? If so, what is that number?

There is no limit. More cores is better. (:

Will ignition use all of them by default, no settings to change to make it use all of them?  
If I had 8 cores will ignition use all of them?

Yup. As long as it has eight things to do. Which it typically will.

Edit: some subsystems use thread pools with specific numbers of threads–if you overload one of those, it will only parallelize that subsystem to the number of its threads.
