Thanks for the advice, Michael!
I'll do some profiling for sure. It's been a while, but my first diagnoses
(which was very useful) was to use the gr performance monitoring tool to
visually see the buffer fullness for each block in the fg. In a naive
implementation, where I added "fill frames" earl
Ron is correct about the defaults.
USB 3.0 has a MTU of 1024 B on the bus and USB 2.0 has a MTU of 512 B, so
you might get something by reducing the send_frame_size to those values. I
recommend also increasing the num_send_frames to something like 256 if you
do. One thing to keep in mind is that
I'm pretty sure the B200 defaults are:
send_frame_size = 8192
num_send_frames = 16

Hi,
I have a GnuRadio modem I've developed and I'd like to reduce latency. It
does IP encapsulation and for testing, I use two USRPs to implement an OTA
connection between the modems.
I've reduced latency so far by 1) adding fill frames/bytes only at the very
last block before the USRP sink and 2
