customize-apropos-options takes forever...

[Drew Adams]

 M-x customize-apropos-options RET RET

On Emacs 22, this takes quite a while. On Emacs 20, it finishes very
quickly.

Emacs 22 has a lot more options, of course, and more faces and buttons and
such, but it still feels like things are less efficient now. In emacs -Q,
there are 4698 lines in the buffer in Emacs 22; in Emacs 20, there are 2333
lines (about half). But Emacs 22 takes *far* longer than twice as long.

[Why would anyone want to customize all options? I don't know, but you might
want to search among option values or something. If you just want
descriptions, `apropos-variable' is of course better (too bad the name
doesn't say "option"). `edit-options' will give you values too, but Emacs
spits a nasty obsoletion message at you (forgetting to put `options' in
quotes, BTW).]
