What are your best optimization tips? Including overclock settings, best emulators, emulator option menu settings, hardware recommendations, etc.

OC to turbo
(i set memory split to 16mb during compile, 256 for regular use)
disable the terminal for serial connection
I only use SSH now, never use samba or the USB copying service (I never install/enable those)
Leave nothing extra plugged into the pi, including the keyboard (i only use a controller)I then run a bash script with “sudo su”:
=====
sed -i ‘s/#hdmi_group=1/hdmi_group=1/g’ /boot/config.txt
sed -i ‘s/#hdmi_mode=1/hdmi_mode=4/g’ /boot/config.txt
echo -e “avoid_safe_mode=1\navoid_pwm_pll=1\nisp_freq=0\nh264_freq=0” >> /boot/config.txt
sed -i ‘s/elevator=deadline/cgroup_enable=memory elevator=noop/g’ /boot/cmdline.txt
echo “CONF_SWAPSIZE=512” > /etc/dphys-swapfile
dphys-swapfile setup
dphys-swapfile swapon
sed -i ‘s/vm.swappiness=1/vm.swappiness=10/g’ /etc/sysctl.conf
echo ‘vm.vfs_cache_pressure=50’ >> /etc/sysctl.conf
sed -i ‘s/defaults,noatime/defaults,noatime,nodiratime/g’ /etc/fstab
apt-get -y remove –purge rsyslog
apt-get -y install inetutils-syslogd

echo -e “*.*;mail.none;cron.none\t -/var/log/messages\ncron.*\t -/var/log/cron\nmail.*\t -/var/log/mail” > /etc/syslog.conf
mkdir -p /etc/logrotate.d

apt-get install -y dropbear openssh-client
/etc/init.d/ssh stop

/etc/init.d/dropbear start

=====Please be careful, if you don’t understand whats going on you probably shouldn’t be using it but it should be safe.
If you are really hardcore:
1. do not use a splash screen
2. delete the simple theme for ES, use no themes!
3. do not use any scraped data for the games
4. compile just what you want, locally on your pi, don’t use the pre-compiled binaries if you don’t have tothe guys who maintain this project have done a REALLY great job at creating an extremely slimmed down image. i would work with that, delete ES/retropie stuff and compile just what i wanted or download just the binaries that i wanted
