I have no idea why that would bog down your machine, but here's my
equivalent version of the same thing -- see if this works? Your use of
`other-window' might be better than my `next-window', which could
potentially yank into a non-visible window.

(defun my-yank-to-other-window (p m)
  "Yank region to point of other window."
  (interactive "r")
  (let ((s (if (use-region-p)
               (buffer-substring-no-properties p m)
             (current-word))))
    (select-window (next-window))
    (insert s)))
