Indeed, thanks. I've made a similar change on the release branch.
[Message part 3 (message/rfc822, inline)]
Starting with emacs -Q:
Evaluate this in the scratch buffer:
;; make the packages list long enough to notice
(when (>= emacs-major-version 24)
(require 'package)
(package-initialize)
(setq package-archives '(("gnu" . "https://elpa.gnu.org/packages/")
("marmalade" . "https://marmalade-repo.org/packages/")
("melpa-stable" . "http://stable.melpa.org/packages/")
("melpa" . "https://melpa.org/packages/")))
(when (not (package-installed-p 'use-package))
(package-refresh-contents)
(package-install 'use-package)))
;; enable mode to cause the problem
(when (>= emacs-major-version 26)
(global-display-line-numbers-mode)
(setq display-line-numbers-type 'visual))
Then run: M-x list-packages
Then click on one of the column headers to trigger sorting by that
column, e.g. Status. Emacs will freeze for a couple of minutes.
Profiler reveals:
- command-execute 25144 98%
- call-interactively 25144 98%
- funcall-interactively 25144 98%
- tabulated-list-col-sort 24960 97%
- tabulated-list--sort-by-column-name 24960 97%
- tabulated-list-print 24956 97%
- apply 24916 97%
- tabulated-list-print-entry 24903 97%
- tabulated-list-line-number-width 24736 96%
#<compiled 0x2a38871> 2 0%
So it looks like all of the time is spent inside tabulated-list-line-number-width.
