Do you realize this is a boolean not a integer? It's either true or false, enhanced idle doesn't poll at all, the kernel inotify or dnotify process watches for filesystem changes in the specified directory then notifies gamin/fam which notifies imapd of any changed files in the watched directory, thus very low resource usage.

The way I often describe it is the difference between the kids in the back seat of the car asking dad every minute "are we there yet?". It's of course much more efficient for Dad to just announce "we're 20 minutes away", "we're pulling into the driveway"..., etc.
