Maybe, I'm not an expert on the matter. The RELNOTES file says the
following for 4.1.0a2:
 "Delayed-ack is now a compile-time option, compiled out by default.
  This feature is simply too experimental for right now, and causes
  some problems to some failover installations.  We will revisit this
  in future releases."

and also the man page:
"Please note that as delayed-ack is currently experimental, the delayed-ack
feature is not compiled in by default, but must be enabled at compile time
with \'./configure --enable-delayed-ack\'."

but in the meantime we're several releases further. I don't know if it
is still accurate.

I think you're right that it's not default-on in dhcpd.conf.

What do you say, enable it always at compile time?

Thanks,
Thomas
