> Currently, the NNThroughputBenchmark acts only as a benchmark of the NN itself. It accesses
the NN directly rather than going via IPC. It would be nice to allow it to run in another
mode where all access goes through the IPC layer, so that changes in IPC serialization performance
can be repeatably/easily measured.
