[Discuss-gnuradio] WX GUI FFT Sink Performance

I figured that one out, but why is the performance so poor? In other applications, I can push over half a million samples without causing issues. Regards, Mark McCarron Date: Sat, 11 May 2013 15:51:56 -0400 From: mle...@ripnet.com To: discuss-gnuradio@gnu.org Subject: Re: [Discuss-gnuradio]
