Currently I am seeing significantly reduced performance when playing videos in Kodi media center on a wired gigbit ethernet home network as compared with the same hardware running amahi 7 "out of the box." Videos that once played without delay or buffering now require 5-10 seconds to access and frequent(a pause every few seconds to few minutes depending on video) pauses for buffering. Most of the video content is mpeg4 720 videos but I have noticed that the larger the video the worse the issue becomes.
I made the changes outlined in your article on samba tuning but only saw a marginal improvement. What I don't understand is that single file transfer rates between the hda and the media center pc are about the same as they were before the upgrade (as rated by the windows file transfer interface). I am noticing some significant latency resolving the hda and then opening the shares (1 to 2 seconds to open a share).
I am not seeing much load on the processor at all. Memory usage for kernal and apps is low but memory caching is consuming remaining available RAM. (4GB total). However, caching takes some time to fill remaining ram space and performance is no better during the period when there is plenty of unallocated space available.
Below is pretty typical.
