Scanning Library damn slow on RasPi4

    My RasPi4 with latest LibreElec get all "local information only" which are stored on my Synology NAS. Unfortunately, since a couple of time the reading speed became extremely slow. It needs at least hours to scan the library (contain roundabout 3500 movies and 300 tv shows).

    RasPi itself is connected via LAN-Cable to Router1 and bridging via WiFi to Router2 (1GBit connection) where my NAS is connected with LAN-cable, too.

    I tried samba and webdav connection and there is no much difference in speed.

    Today, I installed Kodi 19.4 on my Win 10 Laptop and checked scanning speed. Even with WiFi only connection, the speed was increasingly high and the whole library was read within a couple of minutes.

    Any idea why its so slow on RasPi4 and how I can speed it up?

    besides CPU the main limiting factor is SD Card speed, if you are using cheap ones then they likely limiting too

    and the whole library was read within a couple of minutes.

    similar sizes take easily 30min at a powerful device, so its not unusual that it might take a hour or so

    btw dont forget after the first import the scanning is much faster
