-DEXTENDED_NUMERICS This option configures the server to send
extended numerics as well as parse them. This option should only
be used on networks that run ircu2.10.07 and above only.
--DFERGUSON_FLUSHER If you have a server with a lot of resources
-available this option will cause the server to attempt to flush
-it's internal buffers before dropping clients during a netbreak.
-Don't define this if you don't know, if you're not careful this
-can end up rebooting FreeBSD boxes.
-DWALLOPS_OPER_ONLY Setting this option removes the ability for
clients that are not opered to see wallops messages.
+-DNOOPER Disallow the /oper command.

+There are a few to be used for debugging or other networks. These
+should *NOT* be defined on the undernet production network.
+
+-DNICKLEN=15 This allows you do override the default nick length
+to 15 characters. If this has different values on different servers
+your network *WILL* fall apart. Only use this option if you know
+what your doing. If you don't, ask in #coder-com on undernet.
+-DNO_THROTTLE This disables the throttling code. This is used for
+debugging *only*. It lets you connect up to 255 clients from one
+host with no time conciderations. If this is enabled on a
+production server I will personally drive your server into the
+ground. You have been warned.
Operating System and Kernel Requirements:
If you plan allowing more than 1000 clients on your server, you
set rlim_fd_max = 4096
The server will raise the soft limit to the hard limit.
+Linux 2.2 -- [Tri]/Isomer
+The kernel has a kernel destination cache size of 4096. If the kernel sees
+more than 4096 IP's in 60s it warns 'dst cache overflow'. This limit can be
+changed by modifying /proc/sys/net/ipv4/route/max_size.
+A patch to select is also recommended if you have regular poll/select
+errors.
