High CPU on fresh Azure instance (all default config)

[ralftar]

Fresh out of box, all updated, no particular configuration changes, no traffic, the official netgate Azure deployment yields on average a 50%+ CPU load.

Using Diagnostics System Activity i get 100% idle for all processes.

My old on-premises instance using version 2.3.3 runs at 10% with 500 incoming OpenVPN connections (very low traffic). And the hardware specs seems to be the same: Basic A1 (1 vcpus, 1.75 GiB memory)

Is this normal? What is sky rocketing the CPU loads of of the box?
