So do I.
Here are two Emacses (quite old, I'm afraid, bzr 105407, must upgrade):
STIME RSS VSZ
Oct07 832348 1127088
Oct07 226916 499588
The first Emacs does little but run Gnus and BBDB, including a bunch of
gnutls-accessed IMAP mailboxes at my employer's (Drew can probably tell
you *exactly* how that works, even if I use Gnus to access them and he
doesn't), but also including nnml and a bunch of ordinary nntp groups on
multiple servers. No images, no multicharset stuff except whatever I run
across on emacs-devel :)
The second Emacs does no Gnus, but does *all* my software development,
my entire day job, and is much more heavily used, with far more active
buffers, including monsters like a TAGS file for the entire Linux
kernel. Yet its memory consumption is far lower. They have identical
configurations otherwise.
(garbage-collect) for the first:
((2118391 . 1218350) (83106 . 0) (80362 . 45727) 87827825 2736712 (7831 . 20893) (94543 . 15062) (461420 . 158890))
For the second:
((1362224 . 894226) (51114 . 79) (17329 . 6290) 9620209 952486 (747 . 4077) (84546 . 5233) (336029 . 181268))
Gnus is clearly driving Emacs much harder than mere cc-mode ever does.
I'm particularly stunned by the number of string-chars in use. It must
have some huge variables defined, probably holding overview data or
something... I'm not sure how large some of those things are: if they're
large structures this might explain most or all of the memory
consumption.
