[wp-hackers] Permalink Structure - Performance vs. SEO

Leo, if you use /id/category/name it'll find and use the id first without impacting SEO. If you take a look through the archives here, there was a talk about it a couple months back and Matt Cutt's lecture from WP Camp confirmed Google doesn't worry about url depth. But, let me insert the caveat that performance and seo are tough subjects. My understanding on both these points could be wrong and if anybody want's to correct me, I'd love hear it.

Of course if the WordPress team were to add the hook requested in ticket #16992 then this technique could easily be used in a plugin without concern, and also without having to subclass the WP class:
