ok so tested an NFS share, no joy still the same..

then got testing speeds within kodi file manager moving the 500MB file from the local amazon stick to different drives on different machines all on SMB shares and everything using gigabit ethernet. Results were

firestick 4k to SSD | External | internal drives all got approx 22-25 MB/s
any of the drives to firestick 4k all got approx 5-6.5 MB/s

found this a bit weird so tested a normal firestick (jarvis not leia) on the same drives using a 100MB ethernet adaptor. Results were

firestick to all drives approx 8-9 MB/s
any of the drives to firestick all got approx 5-6.5 MB/s

I only have 2.4Ghz wireless, so tested that next on the older firestick (same room as the router) and results were

firestick to all drives approx 3.5 MB/s
any of the drives to firestick all got approx 3.5 MB/s

so what this is telling me (i think) is that it cant get the data from the network quick enough to stop the caching, so the limitation is not with the ethernet adaptor but with the device itself?

has anyone else tried the speed test of moving files over the network to the firestick?
