  Sziasztok,

  Linux Mint 19-et használok.
  Mostanában észrevettem, hogy akadoznak a filmlejátszásaim, akár NFS-ről, akár DLNA-ról, sőt még közvetlenül a gépről lejátszva is bedadog. Nem processzor mert nem nagy közben a kihasználtsága.
  A winyóra tippelek, olyan mint ha bufferelne.
  Futtattam hdparm-ot is.Van ötletetek?
  Itt vannak az eredmények:
