The .vimrc file on your home folder is the vim configuration file. However you can use the next .vim folder structure, also in the home folder:

.vim
  |__vimrc    # configuration file 
  |__after/    # for overrides to system-level vim
  |__autoload/ # a directory for some plugins
  |__colors/   # custom colorthemes
  |__doc/      # documentation
  |__ftplugin/ # custom filetype plugins
  |__indent/   # custom indentation overrides
  |__plugin/   # plugin installation directory
  |__syntax/   # custom syntax coloring files

mkdir -p ~/.vim/autoload ~/.vim/bundle && \
curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim

Recuerda con proxy: curl http_proxy=…

If vim goes too slow do: :syntax off.

You can also try other terminal emulators like Alacritty, Tilda, Kitty, iTerm, Terminal or Hyper.
