That should be the right answer, but is not completely reliable.
Try running test_usrp_standard_rx with different values of the
-D <decim> option. Start with -D 128, then try -D 64, -D 32, -D 16, -D 8.
-D 128 500kS/sec 2MB/sec
-D 64 1MS/sec 4MB/sec
-D 32 2MS/sec 8MB/sec
-D 16 4MS/sec 16MB/sec
-D 8 8MS/sec 32MB/sec
Likewise, try test_usrp_standard_tx with different values of the
-I <interp> option. Start with -I 256, then try -I 128, 64, 32, 16.
-I 256 500kS/sec 2MB/sec
-I 128 1MS/sec 4MB/sec
-I 64 2MS/sec 8MB/sec
-I 32 4MS/sec 16MB/sec
-I 16 8MS/sec 32MB/sec
A couple of over/run-runs at the beginning is OK for any given attempt.
(Note, I just fixed a minor problem that would show 5 or more
tx_underruns at the beginning. Update usrp from CVS if you want the fix.)
