so you try to read a 25MS/s signal from disk? Assuming you use complex floats, this is 8*25MB/s = 200MB/s. Even using complex short is 100MB/s. Most probably your CPU is not working, but waiting - you can use top to see whats going on (us: user process, sy: kernel workload, wa: waiting) Stefan -- Stefan Brüns / Bergstraße 21 / 52062 Aachen phone: +49 241 53809034 mobile: +49 151 50412019 _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
