Maybe the question I need to ask before asking about this is
"what is the best tcp algo to use in the situation where:
1. gigabit fibre on consumer FTTP
2. on a freebsd host whose purpose is hosting bhyve guests"
I expected to load cc_vegas as, from what I've read, it's the
best (most responsive/throughput) for the context but the
reading materials are from 2013 i think.
So, what's in the opinion of the list the best algo in the context?
The second thing is that cc_vegas doesn't build. Latest sources
are main-264125. The OS is at n264089. The kld is missing because
when world was built this kld obviously wasn't. I tried to build directly
just now:
