[Discuss-gnuradio] Has anyone benchmarked GRC vs Matlab/Simulink vs labview ?

We've got an Ettus X310 and are looking at these 3 interfaces: GnuRadio/GRC, Matlab/simulink, and labview. 

Has anyone here ever benchmarked the three for throughput ? If so can you tell us about your benchmark & results.

Surely we're not the first to compare them.

Thanks
