OMG. This is insane.

Go edit your front-page.php, forum.php and view.php templates.

Change

topic_last_poster();

to

echo $topic->topic_last_poster_name;

Cuts mysql queries in half. I went from 50 to under 20.

The data is already in the retrieved topics in memory, there’s no need to reload all the userdata.
