[Discuss-gnuradio] asymmetric USRP throughput

[Vincenzo Pellegrini]

I'm beginning to see some light over my 8MHz tx problems..

the throughput towards my USRP is significantly reduced compared to the
one from it...


./test_usrp_standard_tx
xfered 1.34e+08 bytes in 5.46 seconds.  2.457e+07 bytes/sec.  cpu time =
0.492
0 underruns


./test_usrp_standard_rx
xfered 1.34e+08 bytes in 4.19 seconds.  3.2e+07 bytes/sec.  cpu time = 0.384
noverruns = 0


what could be the cause for this? any hint..? ( benchmark_usb.py reports a good 
throughput up to 32M)

thanks
