Subject: bug#960: 23.0.60; excess consing
Date: Thu, 11 Sep 2008 07:03:35 -0400 [thread overview]
Message-ID: <E1KdjxX-0000d0-4s@fencepost.gnu.org> (raw)
In emacs -Q, I defined these functions to measure consing:
(defun gc-set-base ()
(interactive)
(setq base-cons-cells-consed cons-cells-consed)
(setq base-strings-consed strings-consed)
(setq base-string-chars-consed string-chars-consed)
(setq base-vector-cells-consed vector-cells-consed)
(setq base-symbols-consed symbols-consed)
(setq base-misc-objects-consed misc-objects-consed)
(setq base-intervals-consed intervals-consed))
(defun gc-info ()
(interactive)
(message "C=%s S=%s(%s) V=%s SYM=%s MISC=%s INT=%s"
(- cons-cells-consed base-cons-cells-consed)
(- strings-consed base-strings-consed)
(- string-chars-consed base-string-chars-consed)
(- vector-cells-consed base-vector-cells-consed)
(- symbols-consed base-symbols-consed)
(- misc-objects-consed base-misc-objects-consed)
(- intervals-consed base-intervals-consed)))
(global-set-key [?\M-*] 'gc-info)
Just typing M-* repeatedly I see that cons-cells-consed increases by
about 130, and string-chars-consed increases by around 160. This seems
unreasonably much, for running a command that does no consing itself.
In GNU Emacs 23.0.60.6 (mipsel-unknown-linux-gnu, GTK+ Version 2.12.11)
