Use <network> for Kodi 16 and before
Use <cache> for Kodi 17 and above.
<memorysize> is "xxxMB cache" so convert to bytes, so 200MB is 209715200

Also read the header - The RPi3 may have 1G ram but only about 480MB of that is available.

[Conclusion]
For high bit rate over Ethernet a memorysize of 314572800 and a readfactor of 20 should suffice - as long as no other processes are running and using memory, transmission/SQL etc.

However, if multiple videos are watched, the system may still run out of memory - keep an eye on the memory usage and if it drops to less than 50MB decrease the memorysize by 50MB.

Hello,

I looked in logs I have:
16:49:12.182 T:1962029056 NOTICE: Starting Kodi (17.0 Git:a10c504). Platform: Linux ARM 32-bit

</cache>
</advancedsettings>

...
16:49:12.849 T:1962029056 NOTICE: cache.memorysize: 300MB libass.cache: 0MB

It looks values are used. But when I start playing file I can not see buffering and memory stays the same round 100MB

LibreELEC:~ # free
total used free shared buffers cached
Mem: 753340 281448 471892 5600 40508 129736

I also tried <advancedsettings>
<cache>
<buffermode>1</buffermode>
<memorysize>814572800</memorysize>
<readfactor>40</readfactor>
</cache>
</advancedsettings>

Cannot see any changes

When you change advancedsettings.xml do you reboot each time? Or at least restart kodi to reload the new settings?

Yes, rebooted and tried different versions of advancedsettings.xml with

<advancedsettings>
<network>
<buffermode>1</buffermode>
<cachemembuffersize>139460608</cachemembuffersize>
<readbufferfactor>20</readbufferfactor>
</network>
</advancedsettings>

or
<cache>
<memorysize></memorysize> <!-- number of bytes used for buffering streams in memory
<buffermode></buffermode> <!-- Choose what to buffer:
<readfactor></readfactor>
</cache>

Whatever I tried it only consumes 100Mb from 1000MB available on my pi3

I've just done some tests on a RPi3 7.95.3 using Ethernet and everything is working as expected. (The RPi3 only has 736MB available due to GPU memory allocation, 250 MB it used for the system, leaving only 480MB to play with)
However, I do wonder if Kodi has changed the algorithms for Kodi 17 as I can see no reason why the 3 x memory rule applies.

1st test: Standard TV show
No file - Defaults = 20MB cache readfactor 4
Uses about 10MB ram, very little buffering - about 1 minute.
[hr]
136MB cache readfactor 20.
Uses about 70MB ram - 20 minute buffered
[hr]
200MB cache readfactor 20
Uses about 110MB ram - 30 minute buffered
[hr]
2nd test: 7G movie DTS - Network maxed out around 10,000KB/s filling the cache.
300MB cache readfactor 20
Uses about 180MB ram - 2/3 minutes buffered
[hr]
400M cache readfactor 20
Uses about 230MB ram 5/6 minutes buffered
[hr]
600M cache readfactor 60
Uses about 330MB ram 10 minutes buffered.
[hr]
I can't confirm that they all work reliably, but if something worked in Jarvis, try tripling the values for Krypton and see if that works.

Just to max it: 27GB Bluray m2ts file
600M cache readfactor 60
Used about 450MB leaving only 30MB free - system froze (Probably out of memory)

Thank you, will try today.

What is your <memorysize></memorysize> value in those tests?
Thanks

I also created advancedsettings file and tried increasing memorysize and readfactor with buffermode 1. But it does not influence the memory consumption and it does not improve "Lags" occurring with streaming big files (over 30G) accessed over Samba via Ethernet
