[Discuss-gnuradio] CPU loads and reqs?

[Dave hartzell]

Hi,

I'm curious what CPU and speeds are recommended for some of the USRP
and WxPython apps...

When I run the usrp_wfm_rcv.py application, I get choppy audio,
freezes in the Wx display, and overrun/underruns (OuOuOuOu) characters
on the CLI.  When running Top, I see that "python" and its children
are running about 60% and Xorg is running about 30%.   Running the
no-gui version of this results in clean audio.

The system I'm using is a no-frills Fry's $200 system with extra
memory, running an AMD Sempron 2200+ (whatever marketing-math that
means...).

Clearly this is CPU-limited, what "better" processor would be the best
upgrade?  Intel? AMD?  I'm not sure who has the best FPUs these
days...

Thanks,

Dave
