Intermittent high cpu usage on a windows 2016 file server

Sounds like a process/computer/service is scanning the file structure for a reason, it's not On-Access scanning on Read instead of Write? Do you see a burst in network traffic at the same time or not? (Remote process vs local process)

After other tests, i can see that there is a folder that cause the burst. This folder is part of a share and the problematic folder (let's name it ABC) has more than 7000 subfolder in it root. Each time a folder is created/deleted at the root of ABC, there's an important spike of cpu. Althought the action is taken locally or via the share. This is not happening on other folder on the same share.
I copied the same directory (ABC) on another drive on the server and create a new share. Now there's not problem creating folder with the new location. No more cpu spike.
I cannot explain why.
