I patched the startup.el and package.el in the installed emacs. They seems not work. I'll try to patch the git source prior to the complilation later when I get time.
1. Even I put the (setq package-enable-at-startup nil) in the top of the .emacs, it takes 3.692 sec before loading others of the init file. I have a site-start.el file, which is suposed to run before .emacs is loaded. Woud it impact the the load process? NB. the 3.692 does not count the site-start in. It is from
(message ">>> start load .emacs: %.3f sec <<<"
(float-time (time-subtract after-init-time before-init-time)))
2. No mather whether I set package-enable-at-startup, it takes about 8 sec to load the custom-set-variable. However, it takes only 2.5 sec in the Feb version.
Symbol's value as variable is void: Info-default-directory-list [14 times]
