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?
