This conversion by ghostscript is needed, cause emacs supports PNG
images, but doesn't support some native PDF/PS/DVI rendering.
Joachim Verona currently works on integrating the imagemagick library
with emacs. When that is done, at least zooming in doc-view won't
trigger a new conversion run.

I think that's the only practical solution, else you would have to wait
about a scond when switching to the next page. The doc-view version in
emacs 23 does a pretty good job in hiding the conversion process, for
example by converting from the current page on instead from the first.
Why are many files a problem for you? With that approach, opening a
document for the second time works instantly. And by default those
images are stored somewhere in /tmp:
,----[ C-h v doc-view-cache-directory RET ]
| doc-view-cache-directory is a variable defined in `doc-view.el'.
| Its value is "/tmp/docview1000"
|
| Documentation:
| The base directory, where the PNG images will be saved.
|
| You can customize this variable.
`----
On my system, /tmp is cleaned on startup. And you can always invoke
,----[ C-h f doc-view-clear-cache RET ]
| doc-view-clear-cache is an interactive compiled Lisp function in
| `doc-view.el'.
|
| (doc-view-clear-cache)
|
| Delete the whole cache (`doc-view-cache-directory').
`----
to get rid of the images.
Bye,
Tassilo
