Hi Noam,

Thank you for your patient explaination. I put the (setq package-enable-at-startup nil) in the early-init.el and the load time of .emacs is the same to the emacs Feb version.

It should be explained in `(emacs) Early Init File' and `(elisp) Init
File'.

Not sure, we need to see some more detail to find out.  Can you figure
out if it's all variables getting slower, or is there some specific
variable setting that causes the slowdown?

The package-enable-at-startup setting should be moved to
~/.emacs.d/early-init.el.

Possibly also the settings in site-start.el (since the early-init.el
runs before site-start.el, as described in `(elisp) Startup Summary').
