First post here and my only experience with LibreELEC is on my Raspberry Pi 4, so not sure if this is the case for other LibreELEC builds as well.
Was troubleshooting some streaming stability issues and tweaking the parameters in advancedsettings.xml when I noticed the lines that come with the installation contain something obsolete according to the official KODI wiki:
Since I have already deleted those 3 lines, I don't even remember what the exact names were, but I had to add the following manually as a replacement:
<cache>
<memorysize>xxxxxxxxx</memorysize>
<buffermode>yyyyyyyyyy</buffermode>
<readfactor>zzz</readfactor>
</cache>
And the 3 lines I removed were inside the <network> tag. And they served the same purpose, but should no longer be there as they should now exist in <cache> instead, again according to the KODI wiki pages.
So I am just posting the info here to see if the official LibreELEC build will eventually have updated advancedsettings.xml.
Cheers.
