To optimise the rendering

[Shadow-shadown]

I have 128gb ram and 4 core cpu(do I need to increase my cpu core) in which I want to run the tile server for the entire world
So I want to optimise it as much as Possible
I have used the shm-size to be 80gb and also used flat nodes
But when I want to pre render the tiles and store it there is no mod_tiles or renderer in the docker container
So is there any way to pre render and store the tiles or do I have to install extra dependencies

there is a renderer in the docker container, you can enter the docker container with
docker exec -it <containername> bash
and then pre-render whatever layers you want with
render_list -m default -a -z 0 -Z 4 --num-threads=4
replacing 0 with the highest layer and 4 with the lowest layer you want to render.
