Please *do not apply* the previous patch. Instead, I've attached an
optimized version.
All in all this patch + commit 507244d56b055e7595ba94fe89d45c7ddb2559df
modestly improves the performance of org-publish-org-sitemap. On a
directory of 104 files, it used to take this long...
org-publish-org-sitemap 1 10.508871433 10.508871433
...to generate a sitemap. With this patch and commit 507244d, it takes
this long...
org-publish-org-sitemap 1 7.700290794 7.700290794
Clearly, this is still very inadequate, but it is an improvement. I
would love to use the built in site-map functions, but they are simply
to slow for any larger projects.
Could we do something like this to speed it up?
--8<---------------cut here---------------start------------->8---
(with-temp-buffer
(insert-file-contents file)
(goto-char (point-min))
(when (re-search-forward "^#\\+TITLE:" nil t)
(org-element-at-point)))
--8<---------------cut here---------------end--------------->8---
Until then, here's the patch.

Subject: [PATCH] Protect open buffers when publishing sitemap
* lisp/ox-publish.el: (org-publish-find-title) (org-publish-find-date)
Make sure to call org-export-get-environment in copy of buffer if
emacs is already visiting. Otherwise, #+bind variables meant for
export can be set in live buffers.
This patch also optimizes the above functions by inhibiting
org-startup on buffers emacs visits temporarily.
