Ok I try to shorten my mails, since the information you are asking for is in my last mail (and in some mails before): - ping: < 0.5ms (some peaks every some minutes at 2-3ms), before, during and after video - iperf (600-700Mbit/s), measured with no load - cpu of server at 15-20% while watching video - memory: approx 3-4GB (of 6GB) used, swap all free
Could there be a caching problem, is vlc or parole the "wrong" videoplayer?
