The VERY first thing to do is to use up-to-date versions of the OS's.
And to be clear that this isn't just a platitude, the reason for using the current OS versions is that nicdelay or linksleep or other options that you may find in Chip's presentation if there are others, may not be present or fully developed in 3.8 or 4.4. This has been an active area of development in the last year or so.
