Try re-enabling buffering. Try simplifying your flow, so that you're doing less conversion to various

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.

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?
