Over a few years, I've reached the conclusion that LDM on a gigabit circuit
is really pretty good. When some of the CONDUIT model data streams, you
might become a little backlogged, but it recovers quickly. Generally, while
I was at Texas A&M, we peaked at less than 20Mb/s, regardless of how much
data we were getting in... or how many folks downstream we were feeding.

That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.”
