FOSS gamedev and creative worlds

In singleplayer mode.
I am standing at (0,0,0) and there is a furnace at (0,99,0).
What parameters should I set in minetest.conf so that the furnace does not suspend working?
I think max_block_send_distance and max_block_generate_distance are the most suspicious two.

Its active_block_range, but the performance of the server would be too low if you set it to 7.

Thanks for your time.
I think this performance problem may be a barrier for mods that need prepare before a player reaches.

There is a furnace mod out there that uses the clock for it's cooking instead of an abm. Plus I think there may be a request to merge such a mechanism into the basic minetest game mode. It's been a while since I have seen them but they are there.

Here is a link to the Time Based Furnace mod and the conversation that mentions the merge.
