I'm at a bit of a loss where to ask this question or what might be causing this but as it seems to be a file access problem and as folks around here are cluey on such things here it is..
When trying to play an UHD movie file (55gb file size for ~150min) from my drive pool across a network something can't keep up. I only get a handful of frames per minute and sound is broken or just lost. This behaviour is exhibited from both VLC on my PC (playing from a mapped network drive) or with a direct path from Kodi on my Android TV. When playing the file locally from a USB drive the movie works fine so the playback hardware can cope.
The file is stored on a 4tb WD Red drive and duplicated to another. I've tried with Network I/O Boost and Read Striping both enabled and disabled.
When playing the file, pool read speed jumps all over the place, generally between 1 MB/s - 7.5MB/s
If I copy the file from the network drive onto a local hard drive pool read speed is a solid 80MB/s - 90MB/s (drive read and network speeds seems fine in this case)
The next closest data point I've got is a 1080p movie file, 30gb for ~130min this plays just fine and read speed from the pool typically hovers quite nicely around 4MB/s - 5MB/s.
I'm at a loss as to what would cause this. Any suggestions? Tools that might help diagnose, things I should check etc?
