Roman, I was able to run your code, and got a consistent 150-160 it/s through the whole run, with about 65MB of memory in use (as reporting by Task Manager). This was on Windows 10 running GR 3.8.0.0. I noticed there was another package installed (tqdm) that's not part of the GR install. So I

Hi, huh. That looks hard to debug; also, the slow down is suspicious (as long as there's memory available, it shouldn't take significantly longer to get some – usually, memory fragmentation isn't *that* bad, and this shouldn't be doing *that* much memory allocation). Could you put all your code

Hi Luke, though I like that guide, I'd **really** recommend not building GNU Radio from source on Ubuntu 19.10, unless you really need to (for example, and that's why Ettus has such a guide, because you're using a different UHD than what is available from Ubuntu). On Ubuntu 19.10, it's really
