About this Modpack
Server side modpack that contains only optimization mods, without changing vanilla mechanics or adding new
Note that it can be unstable due async mod. It also has few disabled optimizations in potatoptimized and tt20, because it breaks some farms.
I recommend install this modpack through mrpack4server, because now it is very simple to do
