When clicking on "Manage posts" to view all posts in WP Admin, it takes waaay to long. This is a new WP-site, but we are importing posts from an old site, and currently we have 3,376 posts at the site. But the goal is to import between 10-15.000 articles.
However, if WP is going to reduce the performance like this - it is really critical. It loads 1.5 - 3 minutes (!) before anythis shows up..
The overall performance of the site it self is really good, but the admin-area for posts is a disaster.
1. WHY is the performance so bad
2. How can we make it faster?
