Translator:
SSH and editing the config.txt file is so slow that I had to use my most powerful computer to change a few lines of text. Also, some commands don't work. For example, turning off the LEDs:
# Disable the PWR and Activity LED
dtparam=pwr_led_trigger=none
dtparam=pwr_led_activelow=off
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off
[pi4]
# Disable Ethernet LEDs
dtparam=eth_led0=4
dtparam=eth_led1=4
SSH was very slow with this script.
Now that the only change in the config file is overclocking the RPi4:
over_voltage=2
arm_freq=1800
SSH works pretty well. But it's not perfect anyway.
