It's not a "solution"; you still need to solve your undesirably slow startup, but if you're having to kill and restart Emacs multiple times a day, something is wrong with your workflow. Normally, Emacs doesn't require restart - for weeks and months in some cases. emacsclient is useful on its own. For example, I use it to edit just about any text, in any input box in any app, delegating the task to Emacs, or when I want to open some URL in Emacs, while browsing a web page in my browser, or to send some selected text to Emacs.
