I will add that for an unknown reason the maximum frame size as
reported by UHD when launching the benchmark_rate app is 1556, which
triggers a warning message saying that it should be 8000 for best results.
I cannot find anywhere to set this value to 8000, even when setting
“recv_frame_size=9000,send_frame_size=9000”in the device arguments I
get the same.
As a side note, this maximum frame size value of 1556 is good up to
100Msps dual channel if not using DPDK.
Best,
Guillermo
