To achieve better results using VPN tunnels to the new Raspberry Pi 4, i tried and search to see if it’s possible to overlock this product.
Currently, being a very new one, not too many explanation and support related to this.
Being a fan, today i start to test DietPi, very light os for especially small devices like Raspberry Pi.
1. Cpu usage. Have a look to this:
2. Ram usage:
root@DietPi:~# free -m
total used free shared buff/cache available
Mem: 1989 47 1864 9 77 1855
Swap: 58 0 58
For the overclocking, the maximum possible (where you can receive better results) is to jump from 1500Mhz/core to 1750Mhz/core.
To do that you have to edit /DietPi/config.txt
Here is mine:
#Initial turbo currently leads to CPU not being throttled down by CPU governor: https://github.com/MichaIng/DietPi/issues/1836
force_turbo=0 #settings to one will ignore throttled and will run at maximum
#core_freq=600 #if you want to setup overclocking for GPU
Source and some great explanations.
