I've got the plex media player running locally with the server on the same machine as stablebit. It's buffering every few seconds on low bitrate files (2-10 Mbps), even though the StableBit is showing download speeds around 50-75 Mbps. I'm on Google Drive.
I have 8 download threads, prefetching enabled, 1 MB trigger, 100 MB forward, 600 second window.
Let me know what other information might be useful.
Thanks!
