I used to run Emacs on Linux using Emacsclient, it is really easy and great experience:

emacs --daemon
emacsclient

When I work on a Windows machine, Emacs starts very slow. It seems there's no default support for emacsclient. So I decide to use the use-package package to reduce Emacs startup time. Since there're several packages, I'd like to know which cost the most startup time, and load it with use-package.

If I am not in the right direction, please correct me.
