I use whitespace-mode purely to correct white space when writing files.
Hence, I was using “(whitespace-mode 1)”, but was configuring all the
fonts to black so that I wouldn’t see any incorrect whitespace
characters displayed. Recently, I tracked down extremely poor
performance in c-mode to the fact that whitespace mode was on.

I came up with the following workaround:

1. Add (require 'whitespace) to my .emacs

2. Instead of adding (whitespace-mode 1) to the mode hooks in which I
want whitespace fixing, add (add-hook 'write-file-functions
'whitespace-write-file-hook nil t), which code I copied directly from
whitespace-mode.

I now get whitespace fixing (via the auto-cleanup flag in
whitespace-action) without the slow-down of having whitespace-mode
active. However, this is all a little fiddly. It would be nice if
whitespace-mode could be made to install its hooks without turning
itself on, perhaps by giving a special value to whitespace-mode, e.g. a
symbol like “’only-hooks”?
