Hello Thabet:
There are several possibilities. If you have one or more "file sink" blocks, then your storage I/O speed could be acting as the bottleneck. If you have Python blocks, then they are often the bottleneck of the flowgraph.
If none of the above is true, try running "top -H" while your GNU Radio flowgraph is running. If one GNU Radio block is consuming almost one CPU core, that block is acting as the processing bottleneck. You must somehow reduce the complexity of that block. For
an example, if that block involves FIR filters, then maybe you can try using simpler filter taps.
(also, please consider including discuss-gnuradio as a recipant when replying to the e-mail thread, so as other people can also benefit from the discussion).

I tested hackrf with null souce and it does'nt generate overflows.
So, I use now a native linux (powerful system). My CPU is running at 60% of his capacity but I still have overflows.
Any Idea?
Thanks.
Regards,
Thabet
