You should put a profiler on it to be sure.

Just because your processors aren't processing data doesn't mean they are
idle though -- many have to poll for new data, especially sources -- ex.
connecting to Kafka, etc, will itself consume some CPU.

But again, you should attach a profiler before participating in a wild
goose chase of performance issues.
