Recently after i moved to a new host and upgraded the WP install to 2.3.1 the blog became absolutely sluggish and slow.
The observed behaviour is as follows:
You click on a link and it starts to wait ... wait ... wait and finaly loads in a blink of an eye.
This behaviour is observed on the front page and in the backend too.
The environment is as follows:
apache - 2.2
php - 5.2.0
mysql - 5.0
wp - 2.3.1
plugins - nothing fancy, adsense, search everythig, polyglot, wp-print, geshi
my personal suspicions lie in DB changes, but cant confirm them
