Just curious - how much might gnuradio benefit from running
on 64 bit processors and how much of a rewrite would it take,
to take full advantage of, say, an Athlon 64 X2, seeing as you
could theoretically chunk thru twice the data every bus clock?
I guess the Solaris build doesn't take advantage of the UltraSparc II's.
A little benchmarking with a 300Mhz processor and a short graph:
noise source --> throttle --> low pass filter --> null sink
using 100Khz sample rate and 67 tap filter uses 80% of one cpu.
