It was checked for mainnet at 5777148. It took from 6 to 8 minutes on a laptop. The resulting file is 250 Mb. |

Is your feature request related to a problem? Please describe.
I'm always frustrated when we don't know how long it takes to make a state dump for a real network. Maybe it's seconds, maybe minutes, maybe hours.
Describe the solution you'd like
Traverse MPT for the current state in a special utility (see state sync code that does the same thing effectively) and dump key/value pairs into some file. We need to get an approximate real-life value, so this can be performed on a laptop.
Describe alternatives you've considered
Not a lot. We need to know if it's feasible to create state snapshots on a regular basis.
Additional context
