Please how you achieved no losses on Ubuntu ? I have significantly lower losses
in Ubuntu too but I still have some.
On ubuntu :
Benchmark rate summary:
Num received samples: 131160032
Num dropped samples: 69746238
Num overruns detected: 207
Num transmitted samples: 0
Num sequence errors (Tx): 0
Num sequence errors (Rx): 0
Num underruns detected: 0
Num late commands: 0
Num timeouts (Tx): 0
Num timeouts (Rx): 0
On windows:
Benchmark rate summary:
Num received samples: 95146338
Num dropped samples: 104878018
Num overruns detected: 526
Num transmitted samples: 0
Num sequence errors (Tx): 0
Num sequence errors (Rx): 0
Num underruns detected: 0
Num late commands: 0
Num timeouts (Tx): 0 Num timeouts (Rx): 0
