Also I am happy to see a bunch of "Sponsored by..." Netflix, Yandex, NGINX Inc, Netgate, Citrix, Juniper Networks, Microsoft, Dell, Multiplay, ScaleEngine, etc. in there.
I will say that the release has non-trivial improvements in TCP performance (Mike Karels, Matt Macy, Netflix crew).
VNET jails also should be safe to tear down, and SysV SHM can be jailed/virtualized which should be interesting to many users.
For your average home / small business user? Or do you need to be at Netflix scale to see the benefits? (that's not a bad thing).
There has been a lot of improvement to many network card drivers in 11, and I am helping to push/fund the final integration of Matt Macy's "iflib" for the common intel em/igb/ixgbe drivers.
There are a lot of goodput improvements coming soon, which will affect all TCP users. I had Matt Macy upgrade TCP CUBIC to match 2016 RFC and most Linux behaviors (HyStart). Hiren Panchasara has been working full time for almost 2 years to address many other goodput and correctness issues in the TCP stack. Some of these are in 11, but the majority will hit in 11.1.
Another company is working on the recently announced BBR congestion control from Google and a TCP stack with RACK/PRR https://wiki.freebsd.org/DevSummit/201606/Transport. The end result of all this will be a more tightly integrated and coherent TCP implementation, which should make FreeBSD have the best network stack again in 2017 after falling behind for a while.
You mean I can run multiple postgresql jails on a machine? YASSS
Unfortunately, VNET is still off by default, no?
It's always challenging to put together those highlights... different people consider different things important, and the release engineer has to guess what the largest number of people will care about. (And sometimes things don't end up in the release notes at all because developers forget to flag their commits with "Relnotes: yes", but we're getting better at that.)
Is EFI really that complicated? I also ask because it doesn't seem to me that EFI hasn't really made the PC better for anyone other than Microsoft and Apple.
11.0 doesn't have support for EFI runtime services, but a lot of that has been added to CURRENT (which will become 12.0 and maybe make it into 11.1 via backport) very recently.
