I'd guess you'll first run into disk throughput issues. If you solve those, there still might not be enough overall system (CPU, chipset, memory, I/O) throughput. I don't have any intuition for what the limits might be. How long is your sampling run? Will all the data fit in RAM? -Marc _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
