I am running the flowgraph graph on Windows10 Anaconda 3 GNURADIO 3.10. As it was not even running in my dual booted DragonOS 20.04 gnuradio version 3.8.1.I thought of trying in windows then it worked but not decoding the symbols. It is throwing some pagesize error. But the symbols are overlapping on one another.Below I combined both transmission and reception to decrease latency but no use.

Thanks

I have attached few screen shots

Hi - are you running running under Windows or Linux on the PC.

And are you running a virtual machine?

Check memory usage.

It's possible your using swap as memory-and are constantly swapping the memory to disk - which will slow you to crawl.

It is an adaptive site I changed the blocks accordingly to 3.10 . I am simulating this on my PC. It is lagging like a hell. Can anyone give some tips to increase speed? Or I have to bear with this? The symbols are not getting decided other side due to this

In 3.10 blocks got moved around right? To symbol sync and linear eq stuff?

Bit confused; you're using GNU Radio 3.10, but you specifically read a version of the
tutorial that is marked as *not* applying to 3.10?
