WP-Cache does not help in the saving and editing of pages. Once a “page” is actually saved, it loads at the same speed as the rest of the “posts” on the site.
I’ve experienced similar issues with rewrite_rules (WP 2.2) – more to do with the database ‘max_allowed_packet’ bytes error when saving the rules to the database, but I think it’s the same all round.
On examining the actual rules, it appears that up to 6 rules are inserted for each static page attachment, which to me appeared excessive (for my needs).
So, I looked at the code, and in particular the function page_rewrite_rules (c. wp-includes/rewrite.php, Ln 264), and I changed the call to generate-rewrite_rules() to set the $feed parameter to false:
if( is_array( $attachment_uris ) ) {
foreach ($attachment_uris as $uri => $pagename) {
$this->add_rewrite_tag('%pagename%', "($uri)", 'attachment=');
$rewrite_rules = array_merge($rewrite_rules, $this->generate_rewrite_rules($page_structure, EP_PAGES, true, false));
}
}
This has helped significantly to keep the rewrite rules shorter.
Hopefully this can help someone else too.
