 * Is it still not, performance reasons, a good idea to start your permalink structure
   with the category, tag, author, or postname fields?
 * Is this still valid in 2.9?

 * Hi. This was what I was referring to:
 * > [For performance reasons, it is not a good idea to start your permalink structure with the category, tag, author, or postname fields. The reason is that these are text fields, and using them at the beginning of your permalink structure it takes more time for WordPress to distinguish your Post URLs from Page URLs (which always use the text “page slug” as the URL), and to compensate, WordPress stores a lot of extra information in its database (so much that sites with lots of Pages have experienced difficulties). So, it is best to start your permalink structure with a numeric field, such as the year or post ID. See wp-testers discussion of this topic.](http://codex.wordpress.org/Using_Permalinks#Structure_Tags)

 * I can confirm that there are still performance issues, just as before.
