It's a bit worrying that our new default will require admins to tweak
the server config to provide adequate performance for clients in
the default configuration.
Then again, there's the chicken-and-egg problem. If we don't force
people to push for server-side config changes, they're never gonna
happen...
Though maybe we should wait for one more release cycle before making
serf the default, and tell people that to get most out of httpv2
for 1.7 they should make sure their clients use serf and their
server config is adjusted accordingly?
That would provide some time for a soft transition. It might cause
less pain for those who run into the problem with servers they
do not control.
