[Cin] Render farm - client nvenc and main none, can this work?

Discussed this with GG and he provided the following tips based on a video
that plays in 1 hour running at full speed.  In his final render on an AMD
desktop computer with many threads, he breaks this up into 20 threads using
a local render farm (just the 1 computer) so it only takes about 5 minutes
to render the whole thing  -- in your case on your Ryzen desktop with 16
cores a smaller number would be good.  such as 16 maybe.  One thing he said
to be sure to do to optimize this is to "Reset rates" in the Render Farm
menu so that the jobs are evenly distributed.  In deciding how many threads
to use, he suggests looking at the output of the linux command "top" to see
how much cpu is being actually utilized on a typical render.

Recently however the render times have been becoming a problem. Also, I now

I am not quite sure if I understand this correctly, but I would do all of
your editing on your laptop first and when time to render just move the
project to the desktop and do the final render there using the render farm.

Although I can not test whether a software render farm or a double-machine
nvenc is faster, gg thinks that a localhost render farm would be faster
than using 2 nvenc graphics card enabled computers because there would be
contention on the path to the graphics cards.  It could be slower to have 8
threads using 2 cards than having 16 software threads.  There does not
appear to be a cuda-related speed up available as far as I know.

Perhaps, I have confused this answer.  If so, please reply.
