Slow network performance since QuTS hero h5.2.5.3138

I have a Ts-464 with 16 GB of ram. After I updated to the new release of QuTs, my large MKV files (10-40 GB) have know started buffering in Plex. It may be a coincidence but I have a hunch I’ll need to go to 32 GB of ram if I want to view 2160p movies without buffering.
