Overclock Raspberry Pi 4

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:

CPU usage of Raspberry Pi 4 in DietPi

2. Ram usage:

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:

-------Overclock-------
temp_limit=65
#Initial turbo currently leads to CPU not being throttled down by CPU governor: https://github.com/MichaIng/DietPi/issues/1836
#initial_turbo=20
force_turbo=0 #settings to one will ignore throttled and will run at maximum
over_voltage=2 #requested
arm_freq=1750
#core_freq=600 #if you want to setup overclocking for GPU
#sdram_freq=400
#arm_freq_min=700
#core_freq_min=250
#sdram_freq_min=400

Source and some great explanations.
