[Discuss-gnuradio] File Sink slow?

[Eral Türkyilmaz]

Hello Newsgroup,

I tried to create a simple graph in GRC using a UHD Source (at 2MS/s) and a 
file 
sink which is simply dumping the binary data from the USRPN210.  
I constantly receive Overruns in the form of "O"'s at the console output. 
That should mean the PC isn't able to handle at least 8MB/s to write onto the 
disk.
I also tried to resize the socket buffer according to the instructions. 
I have got a pretty new PC with SATA and an i5(QuadCore).

Can anybody point out where this overruns might come from? 

Thanks and Greets,
Eral Türkyilmaz
