WIP: This takes roughly 35 seconds to add 1GB to the db, which I am not sure is fast enough. I tried a bunch of other methods to speed it up, for example:

larger data chunks in 8mb and 16mb -> took about double the time,
create a file 1Gb file to pass to the container and have the app add that to the db -> then crashed because of the 16mb limit of mysql
a couple other things which either which crashed with a php error or crashed the app

Mariadb / mysql is not in the same container as the PHP process. You'll have to query mariadb stats or something else.

I think the p-r should be recreated to make sure to have a clean diff.

For now there is only 1 comment for sure : the db_size must move and have a sensible default.

This belongs in the LAMPConfig struct and should use the default option. I think 2G is a sensible default for now.
