Roger:
If you're going to push that PI3B/3B+ for max performance, I'd suggest
that you might want to turn off the built-in Bluetooth: Use menu #9
(bash shell) and then edit the basic Pi start-up file with:
nano /boot/config.txt
to insert the following additional line:
dtoverlay=pi3-disable-bt
This hopefully eliminates the power use for, and the stray RF from,
that built-in (and on-by-default) BT radio. If one is not using their
WiFi for connectivity in a PI3, you can add this line as well:
dtoverlay=pi3-disable-wifi
BTW: If you do so, make good note of this as I don't think that Doug's
terrific little file-backup.sh routine addresses this boot startup
control file.
I do this for every PI3 I work on unless we are specifically using
WiFi. There's enough stray RF around, why add to it? When we do want a
second NIC connection on a PI3, we generally use a USB-ethernet adapter
instead of WiFi - but that takes some editing down in the bowls of
ArchLinux to run properly.
Good luck with those UW cables (those backhoes get everywhere),
