things like setting otw_format=sc12 and setting the frame size higher,
but I haven't had any success.
Could you try running your CPU in "performance" mode, rather than the
power-saving 1.6GHz mode that it is apparently running at?

You could perhaps do a "perf top" and see what's consuming time.
The Gnu Radio signal source blocks are not screamingly efficient,
so it may be that they just aren't keeping up, although at 4Msps,
you wouldn't expect them to be too stressed.

Apologies for not forwarding to the full list. I'm attempting to
run the attached flowgraph with the following hardware, but
getting underflows.
I have 8 GB of RAM, so don't think that's a problem. Running
lspci | grep -i usb, I get the following output
00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series
Chipset Family USB Enhanced Host Controller #2 (rev 04)
00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series
Chipset Family USB Enhanced Host Controller #1 (rev 04)
I've attached a copy of cpuinfo.
Thanks!
