Editing Useful Development Info (section)

== Tips for reducing memory and CPU usage ==
* Reduce the systemd-journald max memory usage by editing <code>/etc/systemd/journald.conf</code>, setting <code>Storage=volatile</code> and <code>RuntimeMaxUse=500K</code>.  Without this, it uses around '''5MB'''
* Disable <code>systemd-userdbd</code> with <code>systemctl disable --now systemd-userdbd</code>, you probably don't need this.
* Switch to an alternative network manager, or none at all if you want an offline experience.  While I ship NetworkManager by default, due to it's ease of setup, it is rather bulky, using about '''9MB'''.  Alternative networking managers may be more lightweight.
* Replace <code>/bin/sh</code>'s symlink to <code>bash</code> with one to <code>dash</code>.  Since <code>/bin/sh</code> is meant to be the POSIX conformant shell, applications theoretically shouldn't rely on bashisms to be present.  Replacing it with <code>dash</code> should free up a variable amount of RAM, depending on how many shell instances are running. To do this, <code>pacman -S dash</code> to install it, then, as root, <code>ln -sf dash /bin/sh</code>
* Tips specific to running a graphical environment
** Disable <code>at-spi-dbus-bus</code>, it's a systemd user service.  Unless you're using accessibility features, this is just sitting here sucking up 10MB.  Run <code>systemctl --user mask at-spi-dbus-bus</code>.
** Also, set the <code>GTK_ALLY</code> environment variable to <code>none</code>.  This depends on how your DE/WM handles environment variables.  If running <code>startx</code> from a terminal, where <code>~/.xinitrc</code> is parsed, simply add <code>export GTK_ALLY=none</code> at the top.
** Reboot to apply the changes
* If using <code>pipewire</code> + <code>pipewire-pulse</code>, DON'T! They're significantly slower than standard <code>pulseaudio</code>, which works just as well on the Wii.


'''Note that these do cause the loss of some important functionality'''
* Tips that will break things
** '''If you do this, pipewire will stop working.'''  Disable <code>wireplumber</code>, run the following, <code>systemctl --user disable --now wireplumber</code>, and <code>systemctl --user mask wireplumber</code>.  Without this, it uses '''10MB'''.
