+===== Adjusting memory limits for desktop use =====
+By default the OpenBSD memory limits are quite low, which makes it inconvenient. There are two ways of limiting memory usage, one is the file ''/etc/login.conf'' which defines per-group/user memory limits, and kernel-defined memory limits set by ''sysctl''. If your computer has a lot of memory then you will certainly want to adjust these.
+  *Firstly add your user account to the ''staff'' group, which has the highest memory limits: ''usermod -G staff myuser'' (The default memory limit for ''staff'' can also be adjusted in ''/etc/login.conf'')
+  *Secondly, edit ''/etc/sysctl.conf''
+  *<code>net.inet.ip.forwarding=1
+# default: 1310
+kern.maxproc=8192
+# default: 7030
+kern.maxfiles=32768
