Try simplifying your flow, so that you're doing less conversion to variousforms -- each of those steps costs some number of operations, and your total data flow is 4Msps, because you're looking at two channels of 2Msps.Ok I tried now to dump both channels directly to a file and turned buffering on again. (see http://s14.postimage.org/r5ekme5pd/dump_test.jpg) The whole datarate is now 2*2MS/s = 4 MS/s and the disk writing speed should be at least 2*2MS/s*4byte/S (I and Q) = 16MB/s. I still get some overruns. _______________________________________________ Discuss-gnuradio mailing list address@hidden https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
What is your CPU clock speed?
How much memory do you have?
What type of 1GiGE network interface do you have? This is on an N210?
