Use-package drastically increases load time

[treymerkley]

I started using use-package because spaceline is a pain to work with without it. However, enabling it at least doubled my load time for Emacs, to around ~7 seconds, and the response time is slower than before. I think it has something to do with the Debian base system.

Here's my .init:

;; EMACS init script

;; Garbage
(setq gc-cons-threshold 64000000)
(add-hook 'after-init-hook #'(lambda ()
                               ;; restore after startup
                               (setq gc-cons-threshold 800000)))

;; load pathes for Git pulled packages
;;(add-to-list 'load-path "~/.emacs.d/sublimity/")
(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
(setq package-enable-at-startup nil)
(package-initialize)

  (package-install 'use-package))

Can you enable use-package-verbose, and then show me the load-time from that?

[treymerkley]

Sure. I installed a few new packages, so I'll put in the code with and without the packages that take a while.

With:

Additionally, the big new one that's causing problems I decided to defer with :defer t on it.

Is your Emacs version 24.5? Maybe this is the DNS hang triggered by (indirectly) loading tramp (see Emacs Bug#20015).

[jwiegley]

@treymerkley Do you still think the problem lies with use-package?

[treymerkley]

@jwiegley I don't think so, I think one of my other packages that I enabled at around the same time was making a lot of unnecessary system calls. I replaced the worst offenders and am going to compile from the latest release on GNU's website. It isn't perfect, but it's good enough for me. Thanks!
