Isn't this expected? Auto-revert watches the directory of the file,
so if a lot of changes happen in that directory, Emacs will get a lot
of file-change notifications, and will need to process them.
If you don't like this, customize auto-revert-use-notify to not use
notifications. Or maybe there's some system-wide customization of
inotify that determine the max frequency of inotify notifications when
the changes are to the same file. (I don't know enough about inotify
to say anything more specific, sorry.)
