while : do time bitcoin-cli generatetoaddress 1 <non_local_wallet_address> bitcoin-cli getblockcount done
brings regtest blockgen times up to 600ms when generating a block at the height 120k, even with all empty blocks.
I have noted down the following numbers:
height, gen-time 800 -> 7ms 5500 -> 18ms 11000 -> 31ms 22000 -> 65ms 37000 -> 110ms
and so on.
This makes my test suite slowing down a lot, over time.
Is this something we can deal with?
