Is there a 'set paste' option in Emacs to paste paste from external clipboard?

Question

I am using Emacs on a remote machine which has no X-window through putty. The problem is that the copy/paste from external clipboard(Shift+Ins) is quite slow.

In Vim, there is an option set paste when I need to paste, then is there any similar function for Emacs?

I am currently trying some workarounds: before pasting, I change the major-mode into fundamental-mode, then I disable the minor modes displayed in modeline to make the side effect as minimal as possible. However it is still much slower than when started with emacs -Q. And in the display area(minibuffer), there are messages starting with "matches ... "(parentheses, etc.).

So how to solve it properly?

I don't know of such a "paste mode" for Emacs. You could start with something like the following (new version, using a separate buffer, so that the current buffer's *-change-functions only get called once at the end):

(defvar ttypaste-mode nil)
(add-to-list 'minor-mode-alist '(ttypaste-mode " Paste"))

(defun ttypaste-mode ()
  (interactive)
  (let ((buf (current-buffer))
        (ttypaste-mode t))
    (with-temp-buffer
      (let ((stay t)
            (text (current-buffer)))
        (redisplay)
        (while stay
          (let ((char (let ((inhibit-redisplay t)) (read-event nil t 0.1))))
            (unless char
              (with-current-buffer buf (insert-buffer-substring text))
              (erase-buffer)
              (redisplay)
              (setq char (read-event nil t)))
            (cond
             ((not (characterp char)) (setq stay nil))
             ((eq char ?\r) (insert ?\n))
             ((eq char ?\e)
              (if (sit-for 0.1 'nodisp) (setq stay nil) (insert ?\e)))
             (t (insert char)))))
        (insert-buffer-substring text)))))

If you prefer something a bit more tested and used:

;; enable clipboard interaction between emacs and system
(setq x-select-enable-clipboard t)

It works for me. A simple C-y and you are good to go! Hope that helps.
