 * Actually, I think super cache doesn’t do *anything* for logged in users. So yea
   if you do have allot of co-bloggers or commenters it’s probably best to use Quick
   Cache, although I have never used it before myself.

 * As it turns out, this is normal wordpress behavior..
 * What I did was install WP_Super_Cache to prevent PHP from re-generating pages
   that haven’t been changed.
 * I’m not sure how this affects plugins like StatPress, but I ended up completely
   bypassing PHP by using lighttpd with LUA rewriting. An LUA script now checks 
   if a html page is already generated by WP_Super_Cache and servers that page immediately.
   If not, it continues as it would normally.
 * I can now serve 100 pages per second With the CPU not even reaching 20%. But 
   I don’t think this would be possible with shared hosting since you probably can’t
   install lighttpd with LUA support without root access. Nevertheless, using WP_Super_cache
   will be a big improvement on it’s own!
 * I still wonder why wordpress uses so much CPU to begin with, though…

 * I couldn’t figure out how to get rid of the blank screen so I made a fresh install
   with apache2 + mysql + phpmyadmin + wordpress and nothing else. Then I imported
   the posts from the original wordpress install and this is the result:
 * [http://www.youtube.com/watch?v=97Dnjhw5k5g](http://www.youtube.com/watch?v=97Dnjhw5k5g)
 * Is that load (~80% at 4 to 7 requests per second) normal? It’s an Intel i5-2500
   @ 3.3GHz CPU with 1GB RAM. I imported nothing else except the ~10-or-so posts,
   not even categories.

 * I switched the theme back to TwentyTen and tried both error logging methods, 
   but both php_error.log and wp-content/debug.log remain empty even though they
   are chmodded to 777. I’m assuming that’s because no errors are found.
 * The default theme vs. my own theme made no difference either. I’m currently trying
   to set up another copy on apache2 rather than lighttpd but I keep getting the
   Blank Page of Death with the following errors;
 * Notice: Constant ABSPATH already defined in /var/www/xxx/wp-config.php on line
   35
    Deprecated: Function set_magic_quotes_runtime() is deprecated in /var/www/
   xxx/wp-settings.php on line 32
 * So I’m currently trying to figure that out.
