Tested your suggestion but it does not help. I've tested from 10% up from defaults values up to 10x from default values (following a couple of tuning guides). The only thing I can not test is Ring parameters as I am getting all multicast traffic on lo (loopback) interface. Still checking on RPS and RFS if there is any real use on lo as it is a virtual interface. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
