My init.el takes 4 secs but has no obvious bottleneck?

So I'm profiling my init.el with ESUP and unfortunately I can't find a bottleneck. It's just a sum of small pieces that makes it overall \~3.2 seconds. Note that I'm using use-package with ensure t to enforce lazy loading globally with \`(require 'use-package-ensure)\` and \`(setq use-package-always-ensure t)\`. **UPDATE** It turns out I had ensure, but not defer, set globally. So lazy loading was actually off! Thank you to those who pointed that out. Here's the NEW ESUP output, which still **takes 2.29 secs**.

> Note that I'm using use-package with ensure t to enforce lazy loading globally with `(require 'use-package-ensure)` and `(setq use-package-always-ensure t)`. `:ensure` makes sure the package is installed before it is required. It does not defer the loading of a package on its own. Maybe you're thinking of `use-package-always-defer`?

> Note that I'm using use-package with ensure t to enforce lazy loading globally with `(require 'use-package-ensure)` and `(setq use-package-always-ensure t)`. `ensure` doesn't enforce lazy-loading. It just "ensures" that a package is installed. You want either `:defer t` or the global setting, `(setq use-package-always-defer t)`, which you can override with `:demand t` to explicitly load a package on startup. If you use either `:defer` or the global setting, just make sure you have some way of loading the package when you need it, such as a keybinding that will autoload it.

Thank you pointing this out. I definitely was thinking of always-deferinstead of always-ensure. It turns out that defer was not setglobally, I just set defer globally true via use-package-always-deferand updated the OP. The initialization time reduced from 3.2 to 2.2seconds with the first 2-4 items (easy-mmode, ox, package initialize)being the bottenecks. There's also set-face-attribute andcustom-set-variables but that's fine I guess.

Hej Hej, If I am not mistaken initializing packages is not needed any more. Check out the `package-enable-at-startup` variable. If you do not change the value of this variable to `nil` in your early-init file, you do not have to call `(package-initialize)` Cheers!

You can check my [config](https://github.com/Crandel/home/tree/master/.config/emacs). For me Emacs starts less than second

That first `eval-when-compile` is probably unnecessary. You can replace the ox line with (use-package ox :after org) Not sure about the other one but probably similar idea.

Look into emacs server - client

Thanks, I'll try removing that line for a couple days and see if it introduces any issues. I wasn't sure why I had that line but I tracked it down to the suggested way to load the MELPA repository: https://melpa.org/#/getting-started

Oh, I took that line verbatim from alphapapa, I'll try tinkering around with it and see if it helps [https://github.com/alphapapa/unpackaged.el/blob/007d465798f379e69d76d61628f3a400f7297dea/README.org#export-to-html-with-useful-anchors](https://github.com/alphapapa/unpackaged.el/blob/007d465798f379e69d76d61628f3a400f7297dea/README.org#export-to-html-with-useful-anchors) Thanks!

But how do you do that?! I have the following in my init, which you also have (https://github.com/Crandel/home/blob/master/.config/emacs/init.el#L21), and it takes .60 seconds! eval-when-compile (require 'package) (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t) (package-initialize))

Man 4 seconds is a pipe dream haha!

.004 secs is mighty impressive, do you use the emacs daemon along with emacsclient? or is it a init from scratch?

I have no need for daemon-mode
