Primarily C/C++ source code?

Does that include I/O overhead or is it for data already in memory and/or
L1/L2 caches?  And you really are referring to the rate of _output_ data,
right?  So it's on the order of 600MB/sec for input-data processing speed
(assuming the typical 3x or so compression factor for source code)?

Cool results.

Thanks,
