Are there in the literature or from the Ethereum community/foundation any official benchmark about geth (or any other client, e.g. parity) initial synchronization time (with both fast and normal sync)?
I noticed that this question contain some interesting data, but the geth versions are really old. I would like to have data for geth version > 1.8.x
The official Ethereum blog contains some benchmark on time needed for geth fast synchronization with geth 1.8.0 and geth 1.7.0
