 There's a great optimization thread going on at
 http://www.webmasterworld.com/apache/4053973.htm

 I doubt all or even most of the recommendations would be universally
 compatible, but one thing did jump out at me about this:

 {{{
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
 }}}

 Needs to be changed to:

 {{{
 RewriteRule ^index\.php$ - [S=1]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
 }}}

 Without that change, the internal re-write of index.php after [L] has to
 run through the !-f and !-d conditions, which are supposedly expensive.
