For some reason (which I can't understand, I did not change anything) emacs has become very slow - as in 2 min - at startup. I traced it down to the
require commands of ESS. This is what I have in the
(setq load-path (cons "/usr/share/emacs/site-lisp/ess" load-path)) (require 'ess-site) (require 'ess-smart-underscore) (setq ess-default-style 'DEFAULT)
ess-smart-underscore also loads
ess-site so eliminating the first
require does not change anything. From this question I tried to use
eval-after-load, but this does not work:
In general, I don't care to have ESS loading at startup. I'd be happy if it only loads when I open *.R or *.r files, but I'd like a reasonable startup time. I am running emacs 24.5.1 and ESS 16.04 on Linux. Downgrading to the previous versions of either did not make a difference.
I have now commented everything in
.emacs except for:
(setq load-path (cons "/usr/share/emacs/site-lisp/ess" load-path)) (require 'ess-site)
Then I have reinstalled emacs, ESS, R and updated all the R packages: no difference. I noticed, however, that the first time emacs is launched it is a little bit faster then the following times, which seems odd to me.
