They may be read-only if you're running with securelevel > 0. Otherwise they
"take effect" just fine.

Yes, recompile your kernel with "maxusers 128" or more. This tweaks a bunch
of stuff, notably mbufs.
E.g. with 128 "users" I've got:
226/1920/10240 mbufs in use (current/peak/max):
159 mbufs allocated to data
67 mbufs allocated to packet headers
130/1438/2560 mbuf clusters in use (current/peak/max)
3116 Kbytes allocated to network (9% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
