Feature Request - Optimize scan process

[bedelaitre]

I'm using a Synology DS220+ NAS with 4Go HDD. After hours,
I have more than 20 docker applications including Doku.

When I access to my Doku web page, I can't view anything. I think the scan process take too much time because I've a lot of photo (more than 100.000) in multiple directories.

Not sure how Doku works but if it scans all the directories and all files on the NAS to provide informations, it could be usefull to be able to define directories to ignore.
