Post fitlet-H and memory interleaving
Finally migrated from my fitlet-iA10 to a new fitlet-H, so I could have an internal 2TB
spinning disk. Also moved the 1TB mSATA flash drive, but bought 2 new matched
8GB SO-DIMMs.

Before I did the move, I loaded and ran a memory speed utility. Based on my
knowledge of computers, I expected an improvement due to memory interleaving.
But, I was quite pleased when I got better than 2x performance upgrade. See below.

Note that actual performance can vary based on speed of memory and testing
methods. But in general, the 2 x SO-DIMMs interleaved will perform noticably better
than a single SO-DIMM.

Code:
