[OS X Emacs] Aquamacs 1.4 RC2 performance

[Sebastjan Trepca]

Tried the nightly builds, still the same.

What I noticed is that find-file is snappy, while ido-mode is not.

This is the traceback:

Debugger entered--Lisp error: (quit)
  completing-read("Find file: ~/dev/proj/" (("dummy" 0.1)) nil nil nil
ido-file-history)
  (catch (quote ido) (completing-read (ido-make-prompt item prompt)

nil ... history)))

  ido-read-internal(file "Find file: " ido-file-history nil nil nil)
  (setq filename (ido-read-internal (or item ...) (or prompt "Find
file: ") (quote ido-file-history) default nil initial))
  (if filename nil (setq ido-saved-vc-mt vc-master-templates) (setq

  (unless filename (setq ido-saved-vc-mt vc-master-templates) (setq
filename (ido-read-internal ... ... ... default nil initial)))
  (let (ido-saved-vc-mt (vc-master-templates ...)
(ido-work-directory-index -1) (ido-work-file-index -1)
(ido-find-literal nil)) (unless filename (setq ido-saved-vc-mt
vc-master-templates) (setq filename ...)) (cond (... ...) (... ...)

  (let ((ido-current-directory ...) filename) (if (or ... ...) (setq
filename t ido-exit ...)) (let (ido-saved-vc-mt ... ... ... ...)
(unless filename ... ...) (cond ... ... ... ... ... ... ... ... ...)))
  ido-file-internal(always-frame)
  ido-find-file()
  call-interactively(ido-find-file)

There is some stuff with VC so I disabled it and got about 50%
increase in speed. But it's still not as snappy as in 1.3.
