Bandwidth, latency, and HEXUS.PiFast

The Sisoft Sandra result is much lower than expected, yet consistent over many runs. We can only surmise that the version of Sandra used, v15.72, interpreted the 4GB/6GB anomaly, detailed on the previous page, to the detriment of the score.
However, run Lavalys' Everest 5.0 and the benchmark result is exactly where it should be - around 20GB/s read and 16.5GB/s write.

Latency, though, works out just fine.
